Description

[0001] This application is a divisional application of patent application number 202011341734.8. Technical Field

[0002] This invention relates to seats and seating for passengers, and more particularly to seats and seating for passengers that allow a seat body having a seat back and seat cushion to be switched from a normal state. Background Technology

[0003] Rear seats in vehicles equipped with a switching device have long been known. This switching device is installed on the side portion of the seat back in the width direction of the seat and is used to switch the seat body between a normal position and a folded position that moves it forward from the normal position. Specifically, when the seat body is in the normal position, the locking component of the switching device restricts the relative movement (rotational movement) of the rear seat by engaging with a striker provided on the vehicle body.

[0004] In addition, a rear seat for a vehicle with an armrest (center armrest) has been proposed, which is installed in a manner that allows it to rotate relative to the seat back between a stowed position and an unfolded position that unfolds from the stowed position toward the front of the seat (for example, Patent Document 1).

[0005] In the rear seat of a vehicle described in Patent Document 1, the backrest frame, which serves as the skeleton of the seat back, has a plate-shaped plate frame and a frame-shaped frame installed in front of the plate frame.

[0006] The aforementioned plate frame has a through hole for accommodating the handrail, and the aforementioned frame-shaped frame has an edge frame disposed along the edge of the plate frame, a bridging frame bridging the edge frame and disposed around the through hole, and a reinforcing frame covering a portion of the bridging frame.

[0007] Based on the above configuration, the seat back can ensure the assembly rigidity around the armrests.

[0008] Patent Document 1: Japanese Patent Application Publication No. 2014-19408 Summary of the Invention

[0009] However, in the vehicle seat as described in Patent Document 1, in order to properly maintain the locked state of the locking component installed in the vehicle body, a reinforced structure of the seat back (backrest frame) is required, especially a reinforced structure of the part of the seat back where the switching device is installed.

[0010] For example, there is a need for a reinforced structure that can suppress deformation of the seat back even when a specific load is applied to the car seat during a frontal collision.

[0011] In particular, in the rear seats of a car equipped with a center armrest, a reinforced structure is required for the portion of the armrest that is installed.

[0012] The present invention was made in view of the above-mentioned problems. The object of the present invention is to provide a seat and a seating device that can suppress the overall deformation of the seat back even when a specific load is applied.

[0013] Another object of the present invention is to provide a seating and a vehicle that improves the assembly rigidity with the switching device in a seating system capable of switching the seat body from a normal state.

[0014] Another object of the present invention is to provide a seating and a vehicle that improves the assembly rigidity with a central armrest in a seat having a central armrest.

[0015] The aforementioned problem is solved by the following method. According to the present invention, a seating seat is a seating seat comprising a seat body and a switching device. The seat body has a seat back; the switching device is installed on the side portion of the seat back in the seat width direction and is used to switch the seat body between a normal state in which a occupant can sit and a moving state in which the occupant can move from the normal state. The backrest frame, which serves as the skeleton of the seat back, comprises a main frame, a sub-frame, and a connecting frame. The main frame is composed of a frame body; the sub-frame is arranged side-by-side with the main frame in the seat width direction; the connecting frame is disposed within the frame of the main frame and connects the left and right side frame portions forming the side portion of the main frame in the seat width direction. The switching device, the connecting frame, and the main body portion of the sub-frame extending in the seat width direction are arranged at heights that overlap with each other in the height direction of the seat back.

[0016] Based on the above configuration, it is possible to realize a seating seat that can suppress overall deformation of the seat back even when a specific load is applied.

[0017] In a detailed description, since the switching device and the connecting frame and the main body of the sub-frame extending along the width of the seat are arranged at the same height position in the height direction of the seat back, a seating seat that effectively improves the assembly rigidity with the switching device can be realized.

[0018] In this case, it is preferable that the backrest frame has a plate frame and a reinforcing bracket. The plate frame is installed behind the main frame and the sub-frame and is composed of a plate-like body. The reinforcing bracket connects the connecting frame and the plate frame and extends along the length of the connecting frame.

[0019] Additionally, it is preferable that the backrest frame includes a second reinforcing bracket, which connects the side frame portion and the connecting frame and extends in an inclined direction relative to the extending direction of the side frame portion.

[0020] Based on the above configuration, the rigidity of the backrest frame (especially the main frame) can be further improved with a simple configuration.

[0021] In this case, it is preferable that the reinforcing bracket and / or the second reinforcing bracket are formed in a generally U-shaped cross section and installed in such a way that a portion of the backrest frame is sandwiched between them.

[0022] Based on the above configuration, the assembly of the reinforcing bracket becomes easier, while the rigidity of the backrest frame is improved.

[0023] In this case, it is preferable that on the plate frame, in the main frame and the sub-frame, a plurality of reinforcing protrusions protruding toward the sub-frame are formed on the portion on the side where the sub-frame is installed, and the plurality of reinforcing protrusions are arranged in such a way that the main body of the sub-frame is sandwiched between them in the height direction of the backrest frame.

[0024] Based on the above configuration, the rigidity of the subframe can be further improved.

[0025] At this time, it is preferred that the sub-frame is a frame with a closed cross-section shape, having a sub-frame main body and a sub-frame side part, the sub-frame main body extending along the width direction of the seat; the sub-frame side part is continuously provided at one end of the extension direction of the sub-frame main body and extends towards the height direction of the backrest frame.

[0026] Based on the above configuration, even when a specific load is applied, the subframe can effectively withstand the impact applied to it with a simple configuration.

[0027] In this case, it is preferable that on the panel frame, in the main frame and the sub-frame, a reinforcing rib extending in the height direction of the backrest frame is formed on the portion on the side where the sub-frame is installed, and the side portion of the sub-frame is configured such that it is sandwiched between the reinforcing rib and the main body of the sub-frame in the seat width direction.

[0028] Based on the above configuration, the rigidity of the subframe can be improved, especially the rigidity of the lateral portion of the subframe.

[0029] Preferably, the backrest frame has a shock-absorbing component, which is disposed within the frame of the main frame at a position higher than the connecting frame, and is used to absorb the vibration energy generated by the load when a specific load is applied to the seat back.

[0030] Based on the above configuration, when a specific load is applied to the car seat, the vibration in the backrest frame, especially in the part that is prone to vibration caused by the load, namely the upper position, can be gradually reduced.

[0031] In particular, at the top of the main frame, where the neck and chest of the seated person are supported from behind, it is necessary to reduce the vibration associated with the aforementioned load.

[0032] Preferably, the seat back has a headrest, a secondary headrest, and an armrest respectively disposed on the upper part of the seat back. The headrest is positioned above the main frame; the secondary headrest is positioned above the secondary frame; and the armrest is mounted and positioned on the side of the secondary frame in a manner that allows it to rotate relative to the seat back between a stowed position and an unfolded position. The stowed position is a position where the seat is stowed within a storage space formed by the seat back; and the unfolded position is a position where the seat unfolds from the storage space towards the front of the seat. The secondary headrest is mounted on the armrest.

[0033] Based on the above configuration, a seating seat with an armrest (center armrest) can be realized, which improves the assembly rigidity with the armrest.

[0034] At this time, it is preferable that the armrest frame, which serves as the skeleton of the armrest, has a main frame, a connecting frame, and a second connecting frame. The connecting frame and the second connecting frame are disposed inside the main frame and are connected to form the left and right side frame portions of the seat width direction side of the main frame. The connecting frame and the second connecting frame are disposed at different positions from the sub-frame main portion in the vertical direction.

[0035] Based on the above configuration, the assembly rigidity of the armrest frame relative to the backrest frame can be further improved.

[0036] Furthermore, the aforementioned problem is solved by the following method. A passenger vehicle includes a passenger vehicle seat, a passenger vehicle striker mounted on a passenger vehicle body and engaging with a locking member provided on the passenger vehicle seat, the passenger vehicle striker including a base member, a reinforcing base member, and an engaging member, the base member being mounted relative to the passenger vehicle body; the reinforcing base member being mounted on the base member; the engaging member being mounted on the base member and extending toward the locking member to engage with the locking member, a protruding flange protruding toward the reinforcing base member being formed on the outer periphery of the base member, and a reinforcing flange protruding toward the base member being formed on the outer periphery of the reinforcing base member, the reinforcing base member being installed with a specific space provided on the base member.

[0037] Based on the above configuration, even when a specific load is applied to the seat of the passenger vehicle, it is possible to achieve a passenger vehicle that can further suppress the deformation of the striker of the passenger vehicle.

[0038] In detail, it can improve the rigidity of the base component, especially the base end of the base supporting the engagement component, in the impact pin of a vehicle, resulting in an impact pin for a vehicle that is not easily deformed and is stable.

[0039] According to the present invention, a seating seat can be realized that can suppress overall deformation of the seat back even when a specific load is applied. In detailed description, a seating seat can be realized that effectively improves the assembly rigidity with the switching device.

[0040] Furthermore, according to the present invention, the rigidity of the backrest frame (especially the main frame) can be further improved with a simple configuration.

[0041] Furthermore, according to the present invention, the assembly of the reinforcing bracket becomes easier.

[0042] Furthermore, according to the present invention, even when a specific load is applied, the impact applied to the subframe can be effectively withstood with a simple configuration.

[0043] Furthermore, according to the present invention, the rigidity of the subframe, particularly the rigidity of the lateral portion of the subframe, can be improved.

[0044] Furthermore, according to the present invention, when a specific load is applied to the vehicle seat, the vibration in the backrest frame, especially in the part that is prone to vibration caused by the load, namely the upper position, can be gradually reduced.

[0045] Furthermore, according to the present invention, a seating seat with improved assembly rigidity with the armrest can be realized in a seat having a central armrest.

[0046] Furthermore, according to the present invention, even when a specific load is applied to the seat of the vehicle, it is possible to achieve a vehicle that can further suppress the deformation of the firing pin. Attached Figure Description

[0086] The following is for reference Figures 1-20A Sections 20B will describe embodiments of the present invention.

[0087] The present invention relates to a seating seat, characterized in that: it is a seating seat equipped with a switching device, which is installed on the side portion of the seat back in the seat width direction and is used to switch the seat body between a normal state in which a occupant can sit and a retracted state in which it can be moved from the normal state. The backrest frame, which serves as the skeleton of the seat back, includes a main frame, a sub-frame, and a connecting frame. The main frame is composed of a frame body. The sub-frame is arranged side by side with the main frame in the seat width direction. The connecting frame is arranged within the frame of the main frame and connects the left and right side frame portions that form the side portion of the main frame in the seat width direction. The switching device and the connecting frame are arranged at positions that overlap in the seat width direction with the main body portion of the sub-frame that extends along the seat width direction.

[0088] In addition, the side where the occupant sits is the front side (front side of the vehicle body) relative to the seat back of the passenger seat.

[0089] The passenger seat S is a rear seat, such as the rear seat of a car, and has a main frame and a sub-frame arranged side by side in the width direction of the seat.

[0090] The passenger seat S is a seat that can be configured in two ways: a normal state in which the occupant can sit down and a stowed state in which the seat body is stored in the vehicle floor.

[0091] Specifically, the seated person's operation Figure 1 When the backrest control lever 42 is activated, the seat body tilts forward and folds, switching the passenger seat S from its normal position to a stowed position on the vehicle floor. Alternatively, the passenger can manually pull the seat body upwards to return it to its usable position from the stowed state.

[0092] like Figure 1 As shown, the passenger seat S mainly consists of a seat body, armrests 5, and a switching device 40. The seat body includes a seat back 1, a seat cushion 2, and a headrest 3 (auxiliary headrest 4). The armrests 5 are located in a stowed position within the seat back 1 and extend forward from the stowed position. Figure 2 The switch 40 is installed on the outer part of the seat back 1 in the seat width direction and is used to switch the seat body between the normal state and the folded state.

[0093] In addition, such as Figure 3 As shown, the passenger seat S includes a support base 50, a tilting device 60, and an armrest locking device 70. The support base 50 is mounted on the vehicle floor and supports the seat body (seat back 1). The tilting device 60 is connected in a manner that allows the seat back 1 to rotate relative to the support base 50. The armrest locking device 70 is connected in a manner that allows the armrest 5 to rotate relative to the seat back 1.

[0094] like Figure 1 As shown, the seat backrest 1 is a backrest that supports the back of the seated person from behind, through which it acts as a frame. Figure 3 The backrest frame 10 shown is constructed by placing cushioning material 1a and covering it with skin 1b.

[0095] Seat cushion 2 is the seating area that supports the occupant from below, through which it acts as a skeleton. Figure 3 The padding frame 20 shown is constructed by placing cushioning material 2a on top of cushioning material 2a and covering it with skin 2b.

[0096] Headrest 3 is a headrest that supports the head of the person sitting from behind, through the use of core material Figure 3 The headrest support 3c shown is constructed by placing cushioning material 3a on it and covering it with a cover 3b. The secondary headrest 4 has the same construction.

[0097] Armrest 5 is a component that supports the wrists of the seated person from below, through which it acts as a skeleton. Figure 3 The handrail frame 30 shown is constructed by placing cushioning material 5a and covering it with skin 5b.

[0098] In addition, the handrail 5 has built-in electrical equipment accessories such as lighting and audio equipment 6, making it a larger and heavier handrail than a normal handrail.

[0099] like Figures 3-5 As shown, the backrest frame 10 is composed of a generally rectangular frame that serves as the skeleton of the seat backrest 1. It mainly consists of a frame-shaped main frame 11 made of tubular material, a T-shaped sub-frame 12 arranged side by side with the main frame 11 in the seat width direction, a plate-shaped plate frame 13 installed behind the main frame 11 and the sub-frame 12, and a connecting frame 14 arranged inside the frame of the main frame 11 and connecting the left and right side frame portions 11a and 11b. The side frame portions 11a and 11b constitute the side of the main frame 11 in the seat width direction.

[0100] The main frame 11 and the sub-frame 12 are welded to the front of the plate frame 13 and are arranged adjacent to each other in the seat width direction.

[0101] The main frame 11 is mainly composed of left and right side frame parts 11a and 11b, an upper frame part 11c that connects the upper part of the left and right side frame parts 11a and 11b, and a lower frame part 11d that connects the lower part of the left and right side frame parts 11a and 11b.

[0102] Specifically, the main frame 11 is formed by welding side frame portions 11a and 11b, upper frame portion 11c, and lower frame portion 11d made of U-shaped tubular material.

[0103] The lower frame 11d is a component that is longer in the seat width direction than the upper frame 11c, extending to the sub-frame 12.

[0104] The subframe 12 is a frame made of corner tubes with a closed cross section shape. It mainly consists of a subframe main body 12a extending in the width direction of the seat and a subframe side part 12b connected to and provided at one end of the subframe main body 12a in the extension direction and extending longer in the height direction of the backrest frame 10.

[0105] The main body 12a of the subframe is disposed in the approximately central part of the backrest frame 10 in the height direction, and the side part 12b of the subframe is disposed at the two ends of the backrest frame 10 in the seat width direction, on the opposite side to the main frame 11.

[0106] The subframe main body 12a is arranged to connect the main frame 11 (side frame 11a) and the subframe side part 12b. In addition, the subframe main body 12a and the connecting frame 14 are arranged at the same height in the height direction of the back frame 10.

[0107] In addition, the lower end of the side portion 12b of the subframe is connected to the extended end of the lower frame portion 11d by welding.

[0108] In the main frame 11, at the front of the upper frame 11c, several generally flat surfaces are formed with specific intervals in the seat width direction. A pair of headrest guides 3d for supporting the headrest pillars 3c are installed on the portions forming these generally flat surfaces.

[0109] The main frame 11 is provided with a reinforcing bracket 15A connecting the plate frame 13 and the connecting frame 14, a second reinforcing bracket 15B connecting the side frame part 11a and the connecting frame 14, and a shock-absorbing component 16 disposed above the connecting frame 14 and installed in front of the plate frame 13.

[0110] Additionally, a handrail connecting bracket 17 for connecting the handrail frame 30 is installed on the lower part of the inner side frame portion 11a of the main frame 11, and a padding connecting bracket 18 for connecting the left and right padding frames 20 is installed on the lower part of the outer side frame portion 11b. Multiple base connecting brackets 19 for connecting the support base 50 are installed at the lower end of the lower frame portion 11d.

[0111] Furthermore, a switching device 40 is installed on the upper portion of the outer side frame portion 11b of the main frame 11. This switching device 40 is used to connect to the body mounted on the... Figure 1 The firing pin 44 is shown.

[0112] like Figure 4 , Figure 5 As shown, the reinforcing bracket 15A is a bracket used to reinforce the backrest frame 10, connecting the plate frame 13 and the connecting frame 14 and extending along the length direction of the connecting frame 14.

[0113] The reinforcing bracket 15A is formed in a roughly U-shaped longitudinal section so as to clamp the connecting frame 14 between them.

[0114] Specifically, the reinforcing bracket 15A is composed of a main body wall 15Aa extending along the connecting frame 14, a front wall 15Ab extending downward from both ends of the main body wall 15Aa in the width direction, and a rear wall 15Ac.

[0115] The extended end of the front wall portion 15Ab is welded to the front of the connecting frame 14, and the rear wall portion 15Ac is welded in a state of being sandwiched between the plate frame 13 and the connecting frame 14.

[0116] The second reinforcing bracket 15B is also a bracket used to reinforce the backrest frame 10. It connects the side frame portion 11a and the connecting frame 14 and extends in an inclined direction relative to the extending direction (vertical direction) of the side frame portion 11a.

[0117] The second reinforcing bracket 15B has a roughly U-shaped longitudinal section and is installed in such a way that the side frame portion 11a and the connecting frame 14 are sandwiched between them.

[0118] Specifically, the second reinforcing bracket 15B is composed of a main body wall portion 15Ba extending in the inclined direction, a front wall portion 15Bb extending from both ends of the main body wall portion 15Ba in the width direction inward in the seat width direction, and a rear wall portion 15Bc.

[0119] The extended end of the front wall portion 15Bb is welded to the front of the side frame portion 11a and the connecting frame 14, and the rear wall portion 15Bc is installed in a state sandwiched between the plate frame 13 and the connecting frame 14 (side frame portion 11a).

[0120] like Figure 3 , Figure 5 As shown, the shock-absorbing component 16 is a component used to absorb the vibration energy generated by the load when a specific load is applied to the seat back 1, and is mounted on the plate frame 13 by a mounting bracket 16a.

[0121] The shock-absorbing component 16 is located approximately at the center of the backrest frame 10 (plate frame 13) in the seat width direction.

[0122] For a detailed description, such as Figure 3 As shown, the shock-absorbing component 16 is positioned between the headrest 3 (headrest guide 3d) and the secondary headrest 4 (secondary headrest guide 4d) in the seat width direction. Additionally, as... Figure 5 As shown, it is positioned in the seat width direction to coincide with the position of the reinforcing bracket 15A and the second reinforcing bracket 15B.

[0123] like Figure 3 , Figure 4 As shown, the armrest connecting bracket 17 is a component used to connect the backrest frame 10 and the armrest frame 30. Specifically, it is a component that is welded to the front of the main frame 11 and supports the armrest frame 30 by supporting the armrest rotation shaft 71 and the locked component 82.

[0124] The handrail connecting bracket 17 is a hollow body, formed by combining an inner bracket 17a and an outer bracket 17b disposed on the outside of the inner bracket 17a.

[0125] The inner bracket 17a and the outer bracket 17b are assembled by welding so that their outer edges partially overlap in the seat width direction.

[0126] Specifically, the outer edges of the outer bracket 17b are flange-shaped and extend in opposite directions, with the outer edge of the outer bracket 17b overlapping the outer edge of the inner bracket 17a in such a way that it is fully covered by the outer edge of the inner bracket 17a.

[0127] like Figure 3 As shown, the padding connecting bracket 18 is a stepped plate component extending in the upward and downward direction. The upper part of the padding connecting bracket 18 is installed on the main frame 11, and the lower part is installed on the side of the padding frame 20.

[0128] like Figure 7 As shown, the base connecting bracket 19 is a component used to connect the backrest frame 10 and the support base 50. Specifically, it is fixed to the bottom surface of the main frame 11 by welding and installed on the support base 50 through the backrest rotation shaft 61.

[0129] The base connecting bracket 19 is composed of a bracket body 19a and a bracket reinforcement 19b. The bracket body 19a is composed of a U-shaped plate component with a slender cross-section in the vertical direction; the bracket reinforcement 19b is composed of a plate-shaped component with a slender cross-section in the vertical direction and is clamped by the bracket body 19a.

[0130] In addition, multiple base connecting brackets 19 are installed with gaps in the seat width direction, and connecting lines 19c connecting each base connecting bracket 19 are provided.

[0131] In the bracket body 19a, the portion (lower portion) that differs from the portion (upper portion) where the bracket reinforcement 19b is installed is formed with a narrower width. In other words, in the bracket body 19a, the extension portion extending toward the support base 50 and downward is formed with a narrower width.

[0132] An anchor bolt component 19d for connecting to a child seat (not shown) is installed in the narrower section.

[0133] The anchor bolt component 19d is a roughly U-shaped wire component that is installed from the front of the bracket body 19a to clamp the bracket body 19a.

[0134] Furthermore, since the bracket body 19a and the bracket reinforcement 19b are combined to form a closed cross-section structure, and the bracket body 19a and the anchor bolt component 19d are combined to form a closed cross-section structure, the rigidity of the base connecting bracket 19 is improved.

[0135] In the above composition, such as Figure 5 As shown, in the main frame 11 and the sub-frame 12 on the plate frame 13, a plurality of reinforcing protrusions 13a protruding toward the main frame 11 are formed on the side where the main frame 11 is installed.

[0136] In a detailed description, in the plate frame 13, a reinforcing protrusion 13a is formed in the part where the main frame 11, the connecting frame 14 and the reinforcing bracket 15A are installed.

[0137] Therefore, the assembly rigidity of the main frame 11, connecting frame 14 and reinforcing bracket 15A relative to the plate frame 13 can be improved.

[0138] In addition, in the above composition, such as Figure 5 As shown, a plurality of reinforcing protrusions 13b protruding toward the sub-frame 12 are formed on one side of the plate frame 13 where the sub-frame 12 is installed.

[0139] Multiple reinforcing protrusions 13b are arranged such that the subframe body 12a is sandwiched between them in the height direction of the backrest frame 10.

[0140] Therefore, the rigidity of the subframe 12 can be further improved.

[0141] In addition, in the above composition, such as Figure 5 As shown, a reinforcing rib 13c extending along the height direction of the backrest frame 10 is formed on one side of the plate frame 13 where the sub-frame 12 is installed.

[0142] The reinforcing rib 13c extends upward and downward along the outer periphery of the inner side of the plate frame 13 in the seat width direction. The sub-frame side portion 12b is configured such that it is sandwiched between the reinforcing rib 13c and the sub-frame main body portion 12a in the seat width direction.

[0143] Therefore, the rigidity of the subframe 12 can be further improved.

[0144] In addition, in the above composition, such as Figure 4 As shown, the main body 12a of the subframe 14 and the subframe 12 extending along the width direction of the seat, and the switching device 40 are arranged at height positions that overlap with each other in the height direction of the seat back (same height position).

[0145] Therefore, for example, when a specific load is applied during a vehicle collision, it is possible to realize a passenger seat S that can suppress the overall deformation of the seat back 1.

[0146] In addition, in the above composition, such as Figure 4 As shown, the part (corner) in which the switching device 40 is installed in the main frame 11 has an inclined shape 11e that bends toward the center of the main frame 11.

[0147] Therefore, the assembly rigidity of the switching device 40 relative to the backrest frame 10 can be improved.

[0148] like Figure 3 As shown, the cushion frame 20 is composed of a generally rectangular frame that serves as the skeleton of the seat cushion 2. It mainly consists of left and right side frames 21 arranged on the left and right sides, a front frame 22 connecting the front ends of each side frame 21, a rear frame 23 connecting the rear ends of each side frame 21, a plate-shaped disc frame 24 mounted between the front ends of each side frame 21, and a plurality of elastic springs 25 mounted on the disc frame 24 and the rear frame 23 and extending in a serpentine manner.

[0149] The side frame 21 is a tubular component that extends in the front-to-back direction of the seat. Its front end is connected to the front frame 22 as a whole, and its rear end is connected to the backrest frame 10 through the padding connecting bracket 18.

[0150] A padding rotating device 26 is installed at the rear end of the side frame 21, which is connected to the padding frame 20 in a manner that allows the backrest frame 10 to rotate.

[0151] Additionally, a support foot 27 is installed at the front end of the front frame 22. The support foot 27 is connected to the pad frame 20 in a way that allows it to rotate relative to the vehicle floor and supports the pad frame 20 from below.

[0152] The pad rotation device 26 mainly consists of a pad rotation shaft 26a and a helical spring (not shown) that applies force to the pad frame 20 downward around the pad rotation shaft 26a.

[0153] The padding rotation shaft 26a is axially supported on the backrest frame 10 and the padding frame 20 in the seat width direction. One end of the coil spring is locked on the backrest frame 10 and the other end is locked on the padding frame 20.

[0154] The support foot 27 has a linkage structure that can rotate and move with the rotation of the pad frame 20.

[0155] like Figure 3 , Figure 4 As shown, the armrest frame 30 is composed of a roughly inverted U-shaped frame that serves as the skeleton of the armrest 5. It is installed in front of the backrest frame 10 and positioned in front of the sub-frame 12 via the left and right armrest connecting brackets 17 and the armrest rotation shaft 71.

[0156] The armrest frame 30 can rotate and move between a stowed position stored in the backrest frame 10 and an unfolded position extending from the backrest frame 10 toward the front of the seat, with the armrest rotation axis 71 as the center.

[0157] The armrest frame 30 is mainly composed of a main frame 31, a connecting frame 32 and a second connecting frame 33. The main frame 31 is roughly inverted U-shaped. The connecting frame 32 and the second connecting frame 33 are arranged inside the main frame 31 and are connected to form the left and right side frame parts 31a and 31b of the side of the main frame 31 in the seat width direction.

[0158] Specifically, the handrail frame 30 is constructed by welding together the left and right side frame portions 31a and 31b, which are plate-shaped frames with a roughly U-shaped cross-section, and the upper frame portion 31c, which is a corner tube component with a closed cross-section.

[0159] A handrail rotation shaft 71 connecting the left and right side frame portions 31a and 31b is installed on the lower part of the handrail frame 30.

[0160] Above the upper frame 31c in the main frame 31, a pair of secondary headrest guides 4d are installed to support the secondary headrest support 4c. That is, the secondary headrest 4 is installed on the armrest 5 (armrest frame 30).

[0161] The connecting frame 32 is a plate-shaped frame with a curved shape, and is positioned higher than the second connecting frame 33.

[0162] The connecting frame 32 is composed of a frame body 32a that is slender in the width direction of the seat and left and right frame inclined portions 32b that extend from both ends of the frame body 32a in the length direction outward in the width direction of the seat and tilt towards the rear of the seat.

[0163] The handrail operating lever 72 is mounted between the upper frame 31c and the connecting frame 32 in the vertical direction via the mounting bracket 34.

[0164] In the above composition, such as Figure 4 As shown, the connecting frame 32, the second connecting frame 33 and the handrail rotation shaft 71 are arranged in different positions in the vertical direction than the sub-frame main body 12a.

[0165] In a detailed description, the connecting frame 32, the sub-frame main body 12a, the second connecting frame 33, and the handrail rotation shaft 71 are arranged in a trapezoidal parallel configuration from top to bottom.

[0166] Therefore, the assembly rigidity of the handrail frame 30 can be improved.

[0167] In the above composition, such as Figure 6 As shown, in the left and right side frame portions 31a and 31b, at least the inner side frame portion 31b has a portion through which the armrest rotation shaft 71, the locked component 82 and the locking rotation shaft 83 are installed, and the side frame 35 is reinforced by being installed in an overlapping manner.

[0168] In other words, the part of the side frame portion 31b through which the armrest rotation shaft 71, the locked component 82 and the locking rotation shaft 83 are installed is formed as a double frame, and respectively formed with a circular hole 35a, a boomerang-shaped hole 35b and a circular hole 35c.

[0169] Therefore, by increasing the assembly rigidity of the handrail locking device 70 relative to the handrail frame 30, the handrail 5 can be made to rotate smoothly.

[0170] like Figure 1 , Figure 3 As shown, the switching device 40 is a device for switching the passenger seat S between a normal state and a stowed state, and is installed on the side of the backrest frame 10.

[0171] The switching device 40 mainly consists of a locking component 41, a backrest operating lever 42, and a connecting cable 43. The locking component 41 engages with the strike pin 44 mounted on the vehicle body in a detachable manner and is used to lock the rotational movement of the backrest frame 10. The backrest operating lever 42 is operated to release the locked state of the backrest frame 10. The connecting cable 43 connects the locking component 41 and the backrest operating lever 42.

[0172] In the above description, when the seat body is in a normal state, the switching device 40 can release the locking state of the locking component 41 by operating the backrest operating lever 42.

[0173] After the lock is released, the seat back 1 tilts forward due to the force of the tilting device 60 (coil spring 62), and the seat cushion 2 folds down at the same time, switching to the storage state where it is stored in the vehicle floor.

[0174] like Figure 3 , Figure 7 , Figure 8 As shown, the support base 50 is a base component that supports the seat back 1 from below, and is installed on the lower part of the backrest frame 10 via the base connecting bracket 19 and the backrest rotation shaft 61.

[0175] Specifically, the support base 50 is composed of a base bottom wall portion 51, left and right base side wall portions 52, and left and right base protruding wall portions 53. The base bottom wall portion 51 is composed of a generally inverted U-shaped plate frame and is installed on the vehicle floor by mounting bolts. The left and right base side wall portions 52 extend continuously and curvedly from both ends of the base bottom wall portion 51 in the seat width direction and extend upwards. The left and right base protruding wall portions 53 extend continuously and curvedly from the extended ends of the left and right base side wall portions 52 and protrude forward towards the seat.

[0176] The left and right base protruding wall portions 53 are held in a clamping manner with the base connecting bracket 19 and are connected to the base connecting bracket 19 via the backrest rotation shaft 61.

[0177] In the portion of the base protruding wall 53 that abuts against the base connecting bracket 19, a base protrusion 54 is formed that extends toward a part of the base connecting bracket 19.

[0178] The base extension 54 is configured to pass through the base connecting bracket 19, and extends along the axial direction of the backrest rotation shaft 61 and supports the backrest rotation shaft 61.

[0179] In addition, to improve the rigidity of the support base 50, a reinforcing flange 55 is formed on the outer periphery of the support base 50.

[0180] like Figure 8 , Figure 9A As shown in Figures B and C, the tilting device 60 is a device that rotatably connects the backrest frame 10 and the base connecting bracket 19 relative to the support base 50, and is respectively disposed in the lower part of the left and right side portions of the backrest frame 10.

[0181] The tilting device 60 mainly consists of a backrest rotation shaft 61, a coil spring 62, and an auxiliary spring 63. The backrest rotation shaft 61 extends along the width of the seat. The coil spring 62 applies force to cause the backrest frame 10 to rotate forward around the backrest rotation shaft 61. The auxiliary spring 63 applies force to cause the backrest frame 10 to rotate backward around the backrest rotation shaft 61.

[0182] The backrest rotation shaft 61 is supported by the base connecting bracket 19 and support base 50 on the backrest frame 10 side in the seat width direction. A coil spring 62, an auxiliary spring 63, a washer 64 (interference suppression component) disposed between the coil spring 62 and the auxiliary spring, and a fastening nut 65 (fastening component) disposed at the extended end of the backrest rotation shaft 61 are respectively installed on the outer peripheral surface of the backrest rotation shaft 61.

[0183] The helical spring 62 and the auxiliary spring 63 are configured such that their free ends are engaged with the locking line 66 provided at the lower end of the backrest frame 10 (main frame 11), and their fixed ends are engaged with the slit groove 61b provided on the outer peripheral surface of the backrest rotation shaft 61.

[0184] The helical spring 62 is formed in a wider manner than the auxiliary spring 63, and is a spring that applies greater force than the auxiliary spring 63.

[0185] In addition, the coil spring 62 is mounted on the axial direction of the backrest rotation shaft 61 at a position closer to the center than the auxiliary spring 63.

[0186] With the helical spring 62 and auxiliary spring 63 installed on the backrest rotation shaft 61, the helical spring 62 and auxiliary spring 63 are positioned by tightening the fastening nut 65.

[0187] In the above composition, such as Figure 9A As shown, the tilting device 60 includes a helical spring 62 that applies force to rotate the backrest frame 10 forward, and an auxiliary spring 63 that applies force in the opposite direction to the helical spring 62.

[0188] Therefore, when the seat body (seat backrest 1) is restored from the folded state to the normal state (when it is pulled up), the pulling load is smaller than before, and the pulling action of the seat backrest 1 can be performed smoothly.

[0189] In the above composition, such as Figure 9A As shown, although the fastening nut 65 is tightened when the helical spring 62 and the auxiliary spring 63 are installed on the backrest rotation shaft 61, there are no particular limitations and changes can be made.

[0190] For example, such as Figure 9B , Figure 9CAs shown, with the helical spring 62 and auxiliary spring 63 installed on the backrest rotation shaft 61, the extended end 61a of the backrest rotation shaft 61 can also be used to replace the fastening nut 65 for caulking.

[0191] Additionally, for example, such as Figure 9D As shown, in the case where only the coil spring 62 is installed on the backrest rotation shaft 61, the extended end 61a of the backrest rotation shaft 61 may also be grouted.

[0192] Even with the above configuration, the positioning of the helical spring 62 and the auxiliary spring 63 is still possible.

[0193] Furthermore, the steps for performing caulking on the backrest rotation shaft 61 using the processing device E are as follows: Figures 9E-9G As shown. This step allows the coil spring 62 to be fixed to the extended end 61a of the backrest rotation shaft 61.

[0194] like Figure 3 , Figure 10 As shown, the armrest locking device 70 is a device that connects and locks the armrest frame 30 in a rotatable manner relative to the backrest frame 10, and is installed on the inner side of the armrest frame 30.

[0195] The handrail locking device 70 mainly consists of a handrail locking body 80, a handrail rotation shaft 71, a handrail operating lever 72, and a connecting cable 73. The handrail locking body 80 is used to lock the rotation of the handrail frame 30; the handrail rotation shaft 71 serves as the rotation axis of the handrail frame 30; the handrail operating lever 72 is operated to release the locked state of the handrail frame 30; and the connecting cable 73 connects the handrail locking body 80 and the handrail operating lever 72.

[0196] The armrest rotation axis 71 extends along the width of the seat and is supported on the side of the armrest frame 30 (side frame parts 31a, 31b) and the side of the backrest frame 10 (armrest connecting bracket 17).

[0197] For a detailed description, such as Figure 10 As shown, the armrest rotation shaft 71 is composed of a hollow tube 71a extending in the direction of seat width and a solid shaft 71b extending in the direction of seat width with a portion inserted into the tube 71a.

[0198] The shaft portion of the handrail rotation shaft 71, in which the tube body 71a and the shaft core 71b are assembled, passes through the handrail frame 30 and the handrail connecting bracket 17.

[0199] The armrest operating lever 72 is a lever operated by the seated person, installed on the upper part of the armrest frame 30 and positioned in the center of the armrest frame 30 in the seat width direction.

[0200] The handrail operating lever 72 is able to Figure 11A The normal position shown is different from the position where the seat slides downwards. Figure 11B Switch between the indicated operation positions.

[0201] In addition, the armrest operating lever 72 applies force to the normal position side between the normal position (upper position) and the operating position (lower position) via an elastic spring (coil spring) not shown.

[0202] The connecting cable 73 extends upward and downward within the frame of the handrail frame 30, is pulled by the operation of the handrail operating lever 72, and plays a role in switching the handrail locking body 80 from the locked position to the unlocked position.

[0203] One end 73a of the connecting cable 73 is installed on the handrail operating lever 72, and the other end 73b is installed on the handrail locking body 80.

[0204] like Figure 12 As shown, the handrail locking body 80 mainly consists of a locking component 81, a locked component 82, a locking rotating shaft 83, and a rotating plate 84. The locking component 81 is installed at the other end 73b of the connecting cable 73; the locked component 82 is fixed to the handrail frame 30 and engages with the locking component 81; the locking rotating shaft 83 serves as the rotating shaft of the locking component 81; the rotating plate 84 connects the locking rotating shaft 83 and the handrail rotating shaft 71, and is installed in a manner that allows it to rotate relative to the locking component 81, the locking rotating shaft 83, and the handrail rotating shaft 71.

[0205] In addition, the armrest locking body 80 further includes a force-applying spring 85, which is mounted on the outer peripheral surface of the locking rotation shaft 83 and applies force in a manner that engages the locking member 81 with the locked member 82.

[0206] In the above composition, such as Figure 16 As shown, when the armrest locking body 80 is in the locked position where the locking member 81 and the locked member 82 are engaged, the armrest frame 30 is held in a locked state. On the other hand, as Figure 17 As shown, when the locking member 81 is in the unlocked position where it is not engaged with the locked member 82, the pad frame 20 is held in the unlocked state.

[0207] The locking component 81 is centered on a locking rotation shaft 83 extending in the width direction of the seat. Figure 12 The plate component that rotates between the locked position shown and the unlocked position, which is rotated further back than the locked position.

[0208] When the armrest frame 30 is in the stowed position, the locking component 81 is forced forward by the force spring 85 (towards the locked component 82) and is positioned in the locked position.

[0209] The front portion of the locking component 81 is connected to the other end 73b of the connecting cable 73 via a connecting pin 86, and the rear portion is connected to the locking rotating shaft 83.

[0210] like Figure 13A As shown in Figures B and C, the locking component 81 is a plate-shaped plate with a curved shape, consisting of a main body plate 81a that is slender in the front-to-back direction of the seat and an auxiliary plate 81b that is fixed to the rear part of the main body plate 81a and is slender in the width direction of the seat.

[0211] The main body plate 81a has a cable mounting part 81aa and a shaft mounting part 81ab. The cable mounting part 81aa is formed in the front part of the main body plate 81a and is fitted with the other end 73b (connecting pin 86) of the connecting cable 73. The shaft mounting part 81ab is formed in the rear part of the main body plate 81a and is pivotally locked to the rotating shaft 83.

[0212] A first engaging portion 81ac and a second engaging portion 81ad, which can engage with the locked component 82, are formed at the lower ends of the front and rear portions of the main body plate 81a, respectively.

[0213] When the armrest frame 30 is in the stowed position and the locking member 81 is in the engaged position, the first engaging part 81ac engages with the locked member 82.

[0214] Additionally, when the armrest frame 30 is in the unfolded position and the locking member 81 is in the engaged position, the second engaging part 81ad engages with the locked member 82.

[0215] The auxiliary plate 81b has a caulking part 81ba and a hammer part 81bb. The caulking part 81ba protrudes upward from the outer end in the width direction of the seat and is caulked into the main plate 81a; the hammer part 81bb protrudes downward from the inner end in the width direction of the seat.

[0216] A shaft mounting portion 81bc is formed in a portion of the auxiliary plate 81b where a caulking portion 81ba is formed, and the shaft mounting portion 81bc is formed as a hole communicating with the shaft mounting portion 81ab.

[0217] For example, even when a specific load is applied to the seat S of the passenger vehicle during a rear-end collision, the hammer 81bb becomes the part that functions to maintain the locked state of the locking member 81 and the locked member 82.

[0218] The locked component 82 is a locked shaft that engages with the locking component 81, extends slenderly in the direction of seat width, passes through the armrest frame 30 and is fixed to the armrest connecting bracket 17.

[0219] When the locking member 81 engages with the locked member 82, the first engaging part 81ac (the second engaging part 81ad) of the locking member 81 abuts against the outer peripheral surface of the locked member 82.

[0220] The locking rotating shaft 83 is the rotating shaft of the locking component 81, and extends slenderly in the width direction of the seat. The locking component 81 is rotatably mounted on its outer end in the length direction, and the rotating plate 84 is fixed to its inner end.

[0221] That is, the locking rotating shaft 83 becomes a rotating shaft installed at both ends through the locking component 81 and the rotating plate 84.

[0222] Therefore, good balance can be maintained when the locking rotation axis 83 functions as an axis.

[0223] The rotating plate 84 is a flanged plate with an approximately inverted V-shape, which is rotatably mounted on the outer circumference of the handrail rotating shaft 71. It is a component that is integral with and rotates relative to the handrail rotating shaft 71, the locking rotating shaft 83, the locking component 81, and the force-applying spring 85.

[0224] The force-applying spring 85 is a helical spring wound around the outer circumferential surface of the locking rotating shaft 83, with its free end locked to the connecting pin 86 and its fixed end locked to the side of the handrail frame 30. Furthermore, the force-applying spring 85 applies force to cause the locking member 81 to engage with the locked member 82.

[0225] In the above composition, such as Figure 10 As shown, the shaft portion of the handrail rotation shaft 71, which assembles the tube body 71a and the shaft core 71b, passes through the handrail frame 30 and the handrail connecting bracket 17.

[0226] At this time, the length L1 of the shaft body 71b is longer than the length L2 between the armrest connecting bracket 17 and the rotating plate 84 in the seat width direction.

[0227] In other words, the pivot 71b extends from the armrest connecting bracket 17 through the armrest frame 30 (side frame portion 31b) and elongates to a position beyond the rotating plate 84.

[0228] Therefore, increasing the rigidity of the handrail rotation shaft 71 improves the assembly rigidity of the handrail locking device 70 relative to the handrail rotation shaft 71. As a result, the handrail locking device 70 can operate smoothly.

[0229] In the above composition, such as Figure 12 , Figure 15 As shown, the locking component 82 extends slenderly in the direction of seat width, passes through the armrest frame 30 and is fixed to the armrest connecting bracket 17.

[0230] At this time, the portion of the locked component 82 that passes through the handrail connecting bracket 17 is formed in a wider (thicker) manner.

[0231] Therefore, the assembly rigidity of the locked component 82 relative to the armrest connecting bracket 17 can be improved. As a result, the assembly rigidity of the armrest locking device 70 relative to the backrest frame 10 can be improved.

[0232] In the above composition, such as Figure 15 As shown, a cover plate 90 is installed between the armrest connecting bracket 17 and the armrest frame 30 (side frame portion 31b) in the seat width direction. The cover plate 90 is used to prevent foreign objects from entering the periphery of the armrest rotation shaft 71 and the locked component 82 from the outside.

[0233] Specifically, the cover plate 90 is formed in Figure 6 The boomerang-shaped hole 35b on the side of the side frame portion 31b shown prevents foreign objects from entering the handrail locking device 70.

[0234] The cover plate 90 is a generally elliptical plate with an elongated hole 91 for passing through the armrest rotation shaft 71 and the locked component 82, and a cut hole 92 for avoiding mutual interference with the locking rotation shaft 83.

[0235] <Operation of the armrest locking device>

[0236] Next, based on Figure 16-19 The specific operation of the handrail locking device 70 will be explained.

[0237] First, such as Figure 16 As shown, when the armrest frame 30 is in the "storage position" and the armrest locking body 80 is in the "locked position", the locking component 81 becomes engaged with the locked component 82 (becomes in the "engaged position").

[0238] In a detailed description, the first engaging part 81ac becomes abutted against the outer peripheral surface of the locked part 82 and engages with the locked part 82.

[0239] At this time, the force-applying spring 85 applies force to the locking component 81 toward the locked component 82.

[0240] Then, after the seated person switches the operating lever 72 from the "normal position" to the "operating position", the connecting cable 73 is pulled by the operation of the armrest operating lever 72 and plays a role in switching the armrest locking body 80 from the "locked position" to the "lock released position".

[0241] At this time, as Figure 17As shown, the locking component 81 resists the force applied by the force-applying spring 85 and rotates away from the locked component 82 with the locking rotation axis 83 as the center, changing to a state of disengagement from the locked component 82 (changing to the "disengagement position" state).

[0242] Then, when the armrest frame 30 is moved from the "storage position" to the "expanded position" around the armrest rotation axis 71 by the seated person, as... Figure 18 As shown, the locking component 81 rotates and moves past the locked component 82.

[0243] In this way, even if the seated person's hand leaves the armrest operating lever 72 (even if the armrest operating lever 72 returns from the "operating position" to the "normal position"), the armrest locking body 80 can remain in the "lock-out position".

[0244] Specifically, such as Figure 18 As shown, since the second engaging part 81ad of the locking member 81 slides along the outer peripheral surface of the locked member 82 in a state of abutting against the outer peripheral surface of the locked member 82, the armrest locking body 80 remains in the "lock-out position".

[0245] At this time, the inside of the boomerang-shaped hole 35b of the locked component 82 moves the handrail frame 30.

[0246] Then, as Figure 19 As shown, when the handrail frame 30 moves to the "expanded position", the handrail locking body 80 remains in the "locked-out position" state, and the locking component 81 rotates and moves away from the locked component 82, changing to a state of disengagement from the locked component 82.

[0247] Through the series of actions described above, the armrest 5 moves from the "storage position" to the "expanded position".

[0248] In addition, such as Figure 19 As shown, when the handrail 5 returns to the "storage position", the handrail locking body 80 remains in the "lock-out position". While maintaining this state, the handrail 5 can be pulled to the "storage position".

[0249] When the handrail 5 moves to the "storage position", the handrail locking body 80 switches from the "lock-out position" to the "lock position".

[0250] Specifically, the first engaging portion 81ac of the locking member 81 is brought into contact with the outer peripheral surface of the locked member 82 again, returning to the state of engagement with the locked member 82.

[0251] <Other Implementation Methods>

[0252] In the above embodiments, the storage state of the seat body is described as equivalent to the moving state of the present invention, but it is not particularly limited and can be changed.

[0253] For example, the flipped-up state where the seat cushion 2 jumps upwards can also be regarded as the state corresponding to the moving state of the present invention.

[0254] Alternatively, for example, the seating S for passengers may also include a guide rail device (not shown) that supports the seat body so that it can move in the forward and backward direction. The sliding movement state in which the seat body moves from a normal position to a specific front position (specific rear position) of the seat via the guide rail device can be regarded as the movement state corresponding to the present invention.

[0255] In the above embodiments, such as Figure 1 , Figure 3 As shown, the passenger seat S has armrests 5 and armrest locking devices 70, but it is not particularly limited and may also be a structure without these components.

[0256] Furthermore, the structure of the present invention has a special effect because the passenger seat S has these constituent components.

[0257] That is, it is a seating seat S that can suppress deformation of the seat back 1, especially the part of the seat back 1 where the armrest 5 is assembled, even when a specific load is applied.

[0258] In the above embodiments, such as Figure 13A As shown in Figure B, the locking component 81 consists of a main plate 81a and an auxiliary plate 81b that is fixed to the main plate 81a by a caulking joint, but it is not particularly limited and can be modified.

[0259] For example, such as Figure 20A As shown in Figure B, locking component 181 can be used instead of locking component 81.

[0260] The locking component 181 is a long, thin plate-shaped plate in the front-to-back direction of the seat, with its center of gravity located at the rear.

[0261] Specifically, the locking component 181 has a cable mounting portion 181a, a shaft mounting portion 181b, a first engaging portion 181c and a second engaging portion 181d, and a hammer portion 181e.

[0262] <Second Implementation Method>

[0263] Next, refer to Figures 21-30 The second embodiment of the seat for passengers and the impact pin for passengers will be described.

[0264] The passenger seat S is a rear seat, such as the rear seat of a passenger vehicle (V).

[0265] The passenger seat S is a seat that can be used in two states: a seat where passengers can sit down and a seat that can be folded up.

[0266] like Figure 21 As shown, the passenger seat S mainly consists of a seat body and a switching device 40. The seat body has a seat back 1, a seat cushion 2, and a headrest 3. The switching device 40 is installed on the outer part of the seat body (seat back 1) in the seat width direction and is used to switch the seat body from the use state to the storage state.

[0267] The switching device 40 is a device for switching the passenger seat S from the use state to the storage state, and is installed on the upper part of the seat back 1.

[0268] The switching device 40 mainly includes a locking component 41 and a backrest operating lever 42. The locking component 41 is engaged with the passenger impact pin 101 installed on the vehicle body in a detachable manner. The backrest operating lever 42 is used to switch the locking component 41 between a lockable state in which it can be locked to the passenger impact pin 101 and an unlockable state in which it cannot be locked.

[0269] In the passenger seat S, when in use, if the passenger operates the backrest control lever 42, the locking state of the seat body is released by the switching device 40. With the release of this locking state, the passenger can rotate and fold the seat body towards the front of the seat, and the passenger seat S switches from the use state to the storage state.

[0270] Furthermore, if the passenger wants to return the passenger seat S from the folded state to the usable state, the passenger can switch the seat body to the locked state by resisting the force of the coil spring (not shown) on the seat body and lifting it by hand, thereby engaging the locking part 41 with the passenger strike pin 101.

[0271] like Figures 21-30 As shown, the passenger seat 101 is a component that locks the passenger seat S into a usable state, and is disposed on the side of the vehicle body at a position opposite to the outer part of the passenger seat S in the seat width direction.

[0272] like Figures 23-25As shown, the passenger-carrying impact pin 101 mainly comprises a base component 110, an engaging rod 120, a first reinforcing bracket 130 and a second reinforcing bracket 140, a reinforcing base component 150, and a cover component 160. The base component 110 is mounted relative to the vehicle body. The engaging rod 120 is mounted on the base component 110 and forms a generally U-shape extending elongated toward the locking component 41 for engaging with the locking component 41. The first reinforcing bracket 130 and the second reinforcing bracket 140... The 0 is mounted on the base component 110 and is configured to clamp the engagement rod 120 in a vertical direction perpendicular to the extension direction of the engagement rod 120; the reinforcing base component 150 is mounted on the base component 110 and is configured to partially cover the engagement rod 120 and the reinforcing brackets 130 and 140; the cover component 160 is mounted on the reinforcing base component 150 and is configured to partially cover the engagement rod 120 and the reinforcing brackets 130 and 140.

[0273] like Figures 23-25 As shown, the base component 110 is a base plate fixed to the vehicle body, mainly composed of a base body 111, a rod mounting part 112, a vehicle body mounting part 113, and a protruding flange 114. The base body 111 is generally flat. The rod mounting part 112 is formed in the generally central part of the base body 111 and is used to mount the base end 120a of the engagement rod 120. Multiple vehicle body mounting parts 113 are formed in a manner that surrounds the rod mounting parts 112 and are used to mount the vehicle body. The protruding flange 114 is formed in the outer peripheral part of the base body 111 and protrudes toward the extension end 120b of the engagement rod 120.

[0274] The rod mounting part 112 has two mounting holes for fixing the U-shaped engagement rod 120, and the two mounting holes are configured with a specific interval.

[0275] The rod mounting portion 112 has a protruding shape that extends further toward the extension end 120b of the engaging rod 120 than the base body portion 111.

[0276] Therefore, the assembly rigidity with the engagement rod 120 can be improved. Additionally, as... Figure 29 As shown, the base end 120a of the engagement rod 120 can be configured in a way that does not extend from the base component 110 toward the vehicle body side.

[0277] The body mounting part 113 has multiple mounting holes for fixing the body, and is installed in a state of abutment against the body by using mounting parts (mounting bolts) not shown.

[0278] The protruding flange 114 is formed over approximately the entire area of ​​the outer periphery of the base body 111, in other words, it is formed in a manner that extends along the outer periphery of the base body.

[0279] The protruding flange 114 is constructed such that its protruding height varies depending on the location of the outer periphery. In other words, it forms a stepped shape due to the different protruding heights.

[0280] Specifically, the protruding height of the flange 114 in the front portion of the seat of the base component 110 is greater than the protruding height of the flange 114 in the rear portion of the seat.

[0281] Based on the above configuration, when a specific load is applied to the seat S for passengers, the part that is prone to deformation can be strengthened to transmit stress to the impact pin 101 for passengers.

[0282] like Figures 23-25 As shown, the engagement rod 120 is a U-shaped engagement member that engages with the locking member 41 of the passenger seat S. It mainly consists of a pair of rod extensions 121 extending from the base member 110 side to the passenger seat S side, and a rod connecting part 122 connecting the extension ends of the pair of rod extensions 121.

[0283] The base end 120a of the engagement rod 120 is installed through the rod mounting portion 112 of the base component 110 and further fixed by caulking.

[0284] like Figures 23-25 As shown, the first reinforcing bracket 130 is a plate component with an approximate L-shape, mainly consisting of a mounting wall portion 131 that is mounted to the base component 110 using mounting components (mounting bolts), and an abutting wall portion 132 that extends from the mounting wall portion 131 along the extension direction of the engagement rod 120 and abuts against the engagement rod 120 (rod extension portion 121).

[0285] Furthermore, the connection between the mounting wall portion 131 and the abutting wall portion 132 forms an inclined shape, which improves the rigidity of the first reinforcing bracket 130.

[0286] The second reinforcing bracket 140 has the same structure, mainly consisting of a mounting wall portion 141 and an abutting wall portion 142.

[0287] When the passenger-carrying striker 101 is installed on the vehicle body, the first reinforcing bracket 130 is positioned higher than the second reinforcing bracket 140.

[0288] like Figure 25 , Figure 29 As shown, the first reinforcing bracket 130 and the second reinforcing bracket 140 are fitted together in an abutting state to clamp the engaging rod 120 (a pair of rod extensions 121).

[0289] In addition, such as Figure 25 , Figure 30As shown, the second reinforcing bracket 140 is formed in a wider manner than the first reinforcing bracket 130, and is configured in its width direction to sandwich the first reinforcing bracket 130 between them.

[0290] In detail, the abutting wall portions 132 and 142 have an approximately M-shaped cross-section, with their central portions in the width direction abutting each other, and these abutting portions are fixed by welding. Furthermore, a welding opening 143 is formed in the abutting portion of the second reinforcing bracket 140.

[0291] When these abutting wall portions 132 and 142 are in the abutting state, specific internal spaces are formed at both ends of their width direction, and the engaging rods 120 (a pair of rod extensions 121) are embedded in these internal spaces.

[0292] like Figures 23-25 As shown, the reinforcing base component 150 is a plate component of the reinforcing base component 110, and is installed in a state in which a specific internal space is provided on the base component 110.

[0293] The reinforced base component 150 mainly consists of a base body portion 151, a through hole portion 152, a mounting hole portion 153, a vehicle body mounting portion 154, and a reinforcing flange 155. The base body portion 151 is generally flat. The through hole portion 152 is formed in the general central part of the base body portion 151 and passes through the engagement rod 120 and the reinforcing brackets 130 and 140. The mounting hole portion 153 is formed adjacent to the through hole portion 152 and is used to mount the cover component 160. Multiple vehicle body mounting portions 154 are formed in a manner that surrounds the through hole portion 152 and the mounting hole portion 153 and are used to mount the vehicle body and the base component 110. The reinforcing flange 155 is formed on the outer periphery of the base body portion 151 and protrudes into the base component 110.

[0294] The through hole 152 is wider than the combination of the engagement rod 120 and the reinforcing brackets 130 and 140. That is, the reinforcing base member 150 is configured not to abut against the engagement rod 120 and the reinforcing brackets 130 and 140.

[0295] The portion of the base body 151 that has the through hole 152 and the mounting hole 153 has a protruding shape (protruding portion 151a) that protrudes toward the extended end 120b of the engagement rod 120.

[0296] Therefore, the assembly rigidity of the engagement rod 120 can be improved.

[0297] The body mounting part 154 has a plurality of mounting holes for fixing to the body, and is configured to communicate with the body mounting part 113 (mounting hole) of the base part 110, and is mounted to the body together with the base part 110 using mounting bolts not shown.

[0298] The reinforcing flange 155 is formed by extending along the outer periphery of the base body 151.

[0299] In detail, the reinforcing flange 155 is formed on the front, upper, and lower portions of the outer peripheral portion. Therefore, the rigidity of the impact pin 101 for vehicles can be effectively improved.

[0300] In the above composition, such as Figure 24 As shown, in the outer periphery of the base component 151, reinforcing ribs 156 and stepped uneven portions 157 are formed in a manner that surrounds the through hole 152, the mounting hole portion 153 and the vehicle body mounting portion 154.

[0301] A reinforcing rib 156 is formed on the front portion of the impact pin 101 for use with a passenger vehicle to improve the rigidity of the impact pin 101 for use with a passenger vehicle.

[0302] A stepped, uneven portion 157 is formed in the front portion of the passenger vehicle impact pin 101 and in the rear portion of the passenger vehicle impact pin 101 where the reinforcing flange 155 is not formed.

[0303] like Figure 23 , Figure 25 As shown, the cover component 160 is a resin or rubber cover that partially covers the engagement rod 120, and has the function of suppressing the noise generated by the contact between the passenger seat S (locking component 41) and the passenger striker 101 (engaging rod 120) when they engage.

[0304] The cover component 160 is mainly composed of a cover body 161, a cover flange 162, a cover mounting portion 163, and a through hole portion 164. The cover body 161 has a slender, approximately elliptical cross-section in the extending direction of the engagement rod 120. The cover flange 162 is formed in a radial manner protruding from the base end of the cover body 161 in the diametrical direction. The cover mounting portion 163 is formed on the lower part of the cover flange 162 and is mounted on the reinforcing base component 150 (mounting hole portion 153). The through hole portion 164 is formed on the extending end of the cover body 161 and is used to insert the engagement rod 120.

[0305] like Figure 23 , Figure 30 As shown, the cover body 161 is configured to cover the engagement rod 120 and the reinforcing brackets 130 and 140. Specifically, it is configured to hold the engagement rod 120 and the reinforcing brackets 130 and 140 together.

[0306] In a detailed description, cover protrusions 161a and 161b are formed at both ends of the cover component 160 in the thickness direction on the inner wall surface of the cover body 161, extending close to each other.

[0307] The cover protrusions 161a and 161b are formed in a plurality of spaces at specific intervals in the width direction of the cover member 160. At least a portion of the cover protrusion 161a abuts against the first reinforcing bracket 130, and at least a portion of the cover protrusion 161a abuts against the second reinforcing bracket 140.

[0308] The cover flange 162 is configured to protrude outward from the cover body 161 and has the function of preventing foreign objects from entering the interior of the passenger impact pin 101.

[0309] The cover mounting portion 163 is recessed into the base member 110 via a portion of the cover flange portion 162, and abuts against the reinforcing base member 150 (protrusion 151a).

[0310] The cover mounting part 163 is mounted using a mounting component (mounting bolt) while it is in contact with the mounting hole 153 provided in the protruding part 151a.

[0311] In the above composition, such as Figure 29 As shown, in the ramming pin 101 for vehicles, the protruding flange 114 of the base component 110 and the reinforcing flange 155 of the reinforcing base component 150 are arranged in an orthogonal direction orthogonal to the extension direction of the engagement rod 120.

[0312] In addition, the protruding flange 114 and the reinforcing flange 155 are arranged adjacent to each other, and the reinforcing flange 155 is arranged further out than the protruding flange 114, so as to surround the protruding flange 114.

[0313] Therefore, it is possible to improve the assembly rigidity of the base component 110 and strengthen the base component 150.

[0314] In the above configuration, as shown in 29, the base component 150 has a specific internal space in the portion of the base component 110 where the engagement rod 120 is installed, and is mounted on the base component 110.

[0315] Additionally, a space is formed that is surrounded by the base body 151, which includes the protruding flange 114, the reinforcing flange 155, and the reinforcing base component 150.

[0316] Therefore, the assembly rigidity of the base component 110, the engagement rod 120, and the reinforced base component 150 can be improved. In addition, even if the passenger seat S is subjected to loads from all directions, the deformation of the passenger striker 101 can be easily suppressed.

[0317] In the above composition, such as Figure 29As shown, the reinforcing base component 150 has a through hole 152 for the engagement rod 120 and the reinforcing brackets 130 and 140 to pass through. Furthermore, under normal circumstances, the reinforcing base component 150 is configured not to abut against the engagement rod 120 and the reinforcing brackets 130 and 140.

[0318] On the other hand, when a specific load is applied to the seat S for the passenger, a specific load is also applied to the engagement rod 120 (load transfer), and the engagement rod 120 and the reinforcing brackets 130 and 140 may sometimes bend.

[0319] At that time, the reinforcing base component 150, specifically the outer edge portion of the through hole 152, functions as a movement limiting portion 158 that restricts the deformable movement of the engagement rod 120 and the reinforcing brackets 130 and 140.

[0320] Therefore, even when loads are applied to the vehicle seat from all directions, deformation of the passenger impact pin 101 (especially the engagement rod 120) is easily suppressed.

[0321] In the above composition, such as Figure 23 , Figure 30 As shown, the first reinforcing bracket 130 abuts against the engagement rod 120 (a pair of rod extensions 121) in the longitudinal direction of the vehicle body.

[0322] In addition, the first reinforcing bracket 130 and the second reinforcing bracket 140 abut against each other in such a way that the engaging rod 120 is clamped in the width direction of the vehicle body.

[0323] Furthermore, the second reinforcing bracket 140 clamps the engagement rod 120 and the first reinforcing bracket 130 in the front-rear direction of the vehicle body.

[0324] Therefore, the assembly rigidity with the engagement rod 120 can be improved by strengthening the brackets 130 and 140.

[0325] The objective of the second embodiment described above is to provide a passenger striker that can further suppress deformation even when a specific load is applied to the constituent parts of the passenger (passenger seat).

[0326] In particular, a striker for a vehicle is provided that can suppress deformation even when loads are applied from all directions.

[0327] Therefore, according to the present invention, a preferred type of passenger impact pin is a passenger impact pin 101 that is mounted on one side of the passenger body and the passenger seat S and engages with a locking member provided on the other side of the passenger body and the passenger seat S. It includes a base member 110 mounted relative to said one side, a reinforcing base member 150 mounted on the base member 110, and an engaging member 120 mounted on the base member 110 and extending toward the locking member 41 for engaging with the locking member 41. A protruding flange 114 protruding toward the reinforcing base member 150 is formed on the outer peripheral portion of the base member 110, and a reinforcing flange 155 protruding toward the base member 110 is formed on the outer peripheral portion of the reinforcing base member 150. The reinforcing base member 150 is mounted in a state in which a specific space is provided on the base member 110.

[0328] Based on the above configuration, even if a specific load is applied to the passenger seat S, a passenger striker 101 that can further suppress deformation can be achieved.

[0329] In detail, this improves the rigidity of the base member 110, particularly the base end supporting the engagement member 120, in the vehicle striker 101. As a result, a stable vehicle striker 101 that is not easily deformed can be achieved.

[0330] At this time, a preferred type is a passenger striker 101 that is installed on the main body of the passenger vehicle and engages with the locking member 41 provided on the passenger seat S. The engaging member 120 is a generally U-shaped component, and the protruding flange 114 and the reinforcing flange 155 are arranged in an overlapping position in an orthogonal direction orthogonal to the extension direction of the engaging member 120.

[0331] Based on the above configuration, the rigidity of the impact pin 101 for seating (especially the base component 110) can be improved. As a result, even when a specific load is applied to the seating seat S, deformation of the impact pin 101 for seating can be suppressed.

[0332] At this time, it is preferable that the protruding flange 114 extends along the outer periphery of the base member 110 and the reinforcing flange 155 extends along the outer periphery of the reinforcing base member 150, forming a space surrounded by the protruding flange 114, the reinforcing flange 155 and the main body of the base member 110 or the reinforcing base member 150.

[0333] Alternatively, it is preferred that the protruding flange 114 extends along the outer periphery of the base member 110, and the reinforcing flange 155 extends along the outer periphery of the reinforcing base member 150 and is disposed adjacent to the protruding flange 114.

[0334] Based on the above configuration, the rigidity of the base component 110 can be further improved.

[0335] Furthermore, since flanges are formed on the outer periphery of the base component 110 and the reinforcing base component 150 respectively, deformation of the passenger seat S can be easily suppressed even when loads are applied to the passenger seat S from all directions.

[0336] In this case, it is preferable that the reinforcing flange 155 is positioned further outward than the protruding flange 114 and is arranged to surround the protruding flange 114.

[0337] According to the above configuration, since the reinforcing base member 150 is configured to cover the base member 110 from the outside, the rigidity of the base member 110 can be further improved, and the base member 110 can be protected from the outside.

[0338] At this time, it is preferable to install the base component 150 in a state where a specific space is formed on the portion of the base component 110 where the engaging component 120 is mounted.

[0339] Additionally, it is preferable to further include reinforcing brackets 130 and 140, which are mounted on the base component 110 or the reinforcing base component 150 and configured in an orthogonal direction orthogonal to the extending direction of the engaging component 120 in a manner that clamps the engaging component 120.

[0340] According to the above configuration, the rigidity of the base component 110 can be further improved, and the assembly rigidity of the base component 110 and the meshing component 120 can be further improved.

[0341] At this time, it is preferable that the reinforcing brackets 130 and 140 are mounted on the base component 110 and extend along the extension direction of the engaging component 120. The reinforcing base component 150 is formed with a through hole 152 for penetrating the engaging component 120 and the reinforcing brackets 130 and 140. When a specific load is applied to the engaging component 120, the reinforcing base component 150 restricts the deformation and movement of the engaging component 120 and the reinforcing brackets 130 and 140.

[0342] According to the above configuration, the reinforcing brackets 130 and 140 are arranged to clamp the engaging member 120, and the reinforcing base member 150 is arranged to surround the engaging member 120 and the reinforcing brackets 130 and 140.

[0343] Therefore, even when loads are applied to the passenger seat S from all directions, deformation of the passenger striker 101 (especially the engagement member 120) can be suppressed.

[0344] At this time, it is preferable that at least one of the portions of the base component 110 in which the engaging component 120 is installed and the portion of the reinforcing base component 150 through which the engaging component 120 passes has a protruding shape extending toward the extension of the engaging component 120.

[0345] Based on the above configuration, the assembly rigidity of the base component 110 and the base component 150 and the meshing component 120 can be improved.

[0346] At this time, it is preferable that the reinforcing base member 150 has at least one of the following: a through hole 152 for penetrating the engaging member 120, or a reinforcing rib 156 and a stepped uneven portion 157 disposed at a different position than the through hole 152 and disposed around the periphery of the outer peripheral portion of the reinforcing base member 150.

[0347] Based on the above configuration, the assembly rigidity of the reinforced base component 150 and the base component 110 can be improved.

[0348] <Other Implementation Methods>

[0349] In the above embodiments, such as Figure 21 As shown, the passenger striker 101 is mounted on the vehicle body and engages with the locking component 41 provided on the passenger seat S, but it is not particularly limited and can be modified.

[0350] For example, as a contrasting configuration, the passenger striker 101 may be mounted on the passenger seat S and engaged with the locking member 41 provided on the vehicle body.

[0351] Alternatively, for example, it may be configured such that the passenger striker 101 is installed at a specific location on the vehicle body and engages with a locking component of a vehicle component located outside the vehicle seat.

[0352] In the above embodiments, such as Figure 24 , Figure 25 As shown, the reinforcing brackets 130 and 140 are mounted on the base component 110 and configured to be clamped by the base component 110 and the reinforcing base component 150, but this is not particularly limited and can be changed.

[0353] For example, reinforcing brackets 130 and 140 can also be mounted on reinforcing base component 150. In that case, it is preferable that reinforcing brackets 130 and 140 are fastened to base component 110 together with reinforcing base component 150 using mounting bolts.

[0354] In the above embodiments, such as Figure 25 , Figure 30 As shown, the reinforcing brackets 130 and 140 abut against the engagement rod 120 (a pair of rod extensions 121), but this is not particularly limited. It is also possible that the reinforcing brackets 130 and 140 do not abut against the engagement rod 120, and a number of gaps are formed between them.

[0355] In the above embodiments, such as Figure 29As shown, the reinforcing flange 155 is positioned further out than the protruding flange 114 and is arranged to surround the protruding flange 114, but this is not particularly limited and can be changed.

[0356] For example, the protruding flange 114 can also be configured further out than the reinforcing flange 155 and arranged to surround the reinforcing flange 155.

[0357] Furthermore, if the reinforcing flange 155 is positioned further outward than the protruding flange 114, it forms a structure that easily prevents foreign objects from entering from the outside, which is therefore preferred.

[0358] In the above embodiments, a striker for use in automobiles has been described as a specific example, but it is not particularly limited. In addition to being used as a striker for use in trains, automobiles, etc., it can also be used as a striker for use in airplanes, ships, etc.

[0359] In this embodiment, the seat for passenger use and the striking pin for passenger use involved in the present invention are mainly described.

[0360] However, the above embodiments are merely examples to facilitate understanding of the present invention and are not intended to limit the invention. Without departing from its spirit, the present invention may be modified or improved, and its equivalents are undoubtedly included.
