Detailed implementation mode

[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0028] Below refer to Figures 1 - 5 Describe the seat 100 according to the embodiment of the present invention. One end of the safety belt 101 extends out from the retractor 117 and the other end is fixedly connected to the bottom of the cushion frame 21. The buckle 102 in the middle of the safety belt 101 is further connected to the buckle 241 of the cushion frame 21 to form a three-point fixation. That is, first, a fixing point of the safety belt 101 is set on the seat 100 instead of on the ceiling, which solves the problem that when the seat backrest 1 is adjusted at a large angle, the human body is far away from the safety belt 101 and the safety belt cannot play a protective role. In addition, the lower fixing point of the safety belt 101 is located at the bottom of the cushion frame 21, preventing the fixing point of the safety belt 101 from being set on the covering surface layer 22 of the cushion frame 21, which makes the surface of the seat 100 have a foreign body feeling, thereby improving the comfort of the occupant and enhancing the appearance quality.

[0029] Below refer to Figures 1 - 5 Describe the seat 100 according to the embodiment of the present invention, including: a seat backrest 1 and a seat cushion 2.

[0030] Among them, a retractor 117 is provided inside the seat backrest 1, and a guiding structure 119 is provided at the top of the seat backrest 1. The retractor 117 is connected to one end of the seat belt 101 and is used to retract the seat belt 101. The seat belt 101 is threaded through the guiding structure 119; the seat cushion 2 includes a cushion frame 21 and a covering surface layer 22 located outside the cushion frame 21. The cushion frame 21 includes a rear cushion cross beam 211. A seat belt fixing plate 3 is provided at the bottom of the rear cushion cross beam 211. The other end of the seat belt 101 is threaded through the covering surface layer 22 and extends to the bottom of the rear cushion cross beam 211 to be relatively fixed to the seat belt fixing plate 3.

[0031] In practice, the retractor 117 is provided in the seat backrest 1, and the retractor 117 is connected to the seat backrest 1 through a retractor bracket 118, so that the seat belt 101 is pulled out from the vehicle seat 100 instead of from the vehicle ceiling, which can solve the problem that when the seat backrest 1 is adjusted at a large angle, the human body is far away from the seat belt 101 and cannot provide protection.

[0032] Specifically, the retractor 117 is provided at the rear side of the seat backrest 1, and the guiding structure 119 is provided at the top of the seat backrest 1, which is convenient for the seat belt 101 to directly protect the occupants on the seat 100 after being pulled out from the guiding structure 119. Among them, the seat cushion 2 includes a rear cushion cross beam 211, which is the cross beam close to the seat backrest 1. A seat belt fixing plate 3 is connected to the bottom of the rear cushion cross beam 211. The seat belt 101 in the embodiment of the present invention is a three-point seat belt 101. One fixing point of the seat belt 101 is at the retractor 117, and the other fixing point is at the seat belt fixing plate 3 of the rear cushion cross beam 211. A locking piece 102 is provided between the seat belt fixing plate 3 and the retractor 117 of the seat belt 101, and a buckle mounting bracket 24 is provided on the cushion frame 21 for fixing the buckle 241. When in use, the locking piece 102 is inserted into the buckle 241.

[0033] In the embodiment of the present invention, one end of the seat belt 101 is mainly connected to the bottom of the rear cushion cross beam 211 through the covering surface layer 22 of the seat cushion 2 and from one side of the cushion frame 21, so that the position where the seat belt 101 passes through the covering surface layer 22 is moved backward and the lower fixing point of the seat belt 101 is hidden, which can also solve the foreign body sensation caused by the fixing point of the seat belt 101 in the prior art being located on the covering surface layer 22. By setting one fixing point at the bottom of the rear cushion cross beam 211, the comfort of the occupants is improved and the appearance quality is enhanced.

[0034] In some embodiments, the cushion frame 21 further includes a plurality of cushion longitudinal beams 212, and the seat belt fixing plate 3 is fixedly connected to the rear cushion cross beam 211 and one of the cushion longitudinal beams 212.

[0035] In practice, the seat cushion frame 21 is provided with a plurality of seat cushion longitudinal beams 212. Connecting the seat belt fixing plate 3 to the rear seat cushion cross beam 211 and one of the seat cushion longitudinal beams 212 can improve the connection strength of the seat belt fixing plate 3, so that the seat belt 101 is more reliably connected to the bottom of the seat cushion frame 21, improving the safety of the seat belt 101.

[0036] Referring to Figure 3 As shown, the area where the seat belt fixing plate 3 is connected to the rear seat cushion cross beam 211 is larger than the area where it is connected to the seat cushion longitudinal beam 212. And one end of the seat belt 101 is connected to the position of the seat belt fixing plate 3 on the rear seat cushion cross beam 211. In addition, a through hole 221 is provided at the position where the covering surface layer 22 is close to the seat back 1, that is, one end of the seat belt 101 extends out of the through hole 221 at the position where the covering surface layer 22 is close to the seat back 1 and is fixedly connected to the seat belt fixing plate 3. Thus, connecting one end of the seat belt 101 to the position of the seat belt fixing plate 3 on the rear seat cushion cross beam 211 can more conveniently fix the connection between the seat belt 101 and the seat belt fixing plate 3.

[0037] In some embodiments, the rear seat cushion cross beam 211 is provided with a notch 2111, and the seat belt fixing plate 3 is connected to the rear seat cushion cross beam 211 at the notch 2111 and partially extends to connect to the seat cushion longitudinal beam 212.

[0038] That is to say, by providing the notch 2111 at the rear cross beam, the part of the seat belt fixing plate 3 connected to the rear seat cushion cross beam 211 blocks the notch 2111 and partially extends to the position of the seat cushion longitudinal beam 212. After the seat belt fixing plate 3 is connected to the rear seat cushion cross beam 211, it is equivalent to the seat belt fixing plate 3 being a part of the rear seat cushion cross beam 211, and it also prevents the thickness of the seat belt fixing plate 3 and the rear seat cushion cross beam 211 from being too large when stacked. When the installation belt fixing plate 61 and the rear seat cushion cross beam 211 are stacked and then one end of the seat belt 101 is installed again, the seat belt 101 protrudes more from the rear seat cushion cross beam 211, resulting in poor flatness and occupying a certain space. Therefore, by providing the notch 2111 at the rear seat cushion cross beam and connecting the seat belt fixing plate 3 to the notch 2111 and partially extending to the seat cushion longitudinal beam 212, after the seat belt 101 is connected to the seat belt fixing plate 3, the flatness of the rear seat cushion cross beam 211 is improved. For example, the seat belt fixing plate 3 can be welded to the bottom surfaces of the rear seat cushion cross beam 211 and one of the seat cushion longitudinal beams 212.

[0039] In some embodiments, the seat belt fixing plate 3 is provided with a groove 31, and the groove 31 is recessed toward the position where the rear seat cushion cross beam 211 has the notch 2111. One end of the seat belt 101 includes a fixing piece 4, and the fixing piece 4 is fixedly connected to the seat belt fixing plate 3 at the groove 31.

[0040] In practice, by providing a groove 31 in the seat belt fixing plate 3, after the fixing piece 4 of the seat belt 101 is connected to the groove 31, the fixing piece 4 can be better hidden in the groove 31, effectively reducing the space occupied by the lower fixing point of the seat belt 101 on the seat 100. In addition, a notch 2111 is provided at the rear cross beam 211 of the seat cushion. The position of the groove 31 of the seat belt fixing plate 3 corresponds to the position of the notch 2111 provided at the rear cross beam 211 of the seat cushion, which makes it more convenient to provide the groove 31, provides space for providing the groove 31 for the seat belt fixing plate 3, and provides a basis for saving space for the lower fixing point of the seat belt 101.

[0041] Referring to Figure 3 As shown, an open mouth is provided on one side of the groove 31 close to the seat backrest 1. After passing through the covering layer 22 outside the seat cushion frame 21, the fixing piece 4 of the seat belt 101 faces the bottom of the seat cushion frame 21, and the fixing piece 4 extends into the groove 31 along the open mouth of the groove 31, and the fixing piece 4 is connected to the groove 31 by bolts, realizing the connection of one end of the seat belt 101 to the position of the groove 31, thereby effectively reducing the space occupied by the lower fixing point of the seat belt 101 on the seat 100.

[0042] In some embodiments, the plurality of seat cushion longitudinal beams 212 include end longitudinal beams and at least two middle longitudinal beams. A first transverse reinforcing member 213 is provided between the two middle longitudinal beams. The first transverse reinforcing member 213 is parallel to the rear cross beam 211 of the seat cushion, and the two middle longitudinal beams and the first transverse reinforcing member 213 form a first reinforcing structure.

[0043] In practice, a first reinforcing structure of the seat cushion frame 21 is formed by connecting the two middle longitudinal beams and the first transverse reinforcing member 213. That is, the first reinforcing structure is an H-shaped reinforcing structure. The H-shaped reinforcing structure improves the stability and strength of the seat cushion frame 21 and can reduce the longitudinal and transverse deformation of the seat cushion frame 21.

[0044] Referring to Figure 2 and Figure 3As shown, the H-shaped reinforcement structure is located in the middle of the entire seat cushion frame 21, so that the entire seat cushion frame 21 is balanced in force; one of the middle longitudinal beams in the H-shaped reinforcement structure is a non-linear longitudinal beam, and includes a connected first section 2121, an inclined section 2122 and a second section 2123 along the length direction. The first section 2121 and the second section 2123 are parallel and staggered. The inclined section 2122 connects the parallel first section 2121 and the second section 2123. The other middle longitudinal beam of the H-shaped reinforcement structure is constructed as a linear longitudinal beam, that is, the first section 2121 and the second section 2123 of the non-linear longitudinal beam are respectively parallel to the linear longitudinal beam, and the distance between the first section 2121 and the linear longitudinal beam is less than the distance between the second section 2123 and the linear longitudinal beam. The first section 2121 is connected to the side close to the seat backrest 1, and the second section 2123 is connected to the side far from the seat backrest 1. And the first transverse reinforcement 213 is located on one side of the center of the seat cushion frame 21 and close to the seat backrest 1, thereby improving the strength of the connection between the seat cushion frame 21 and the backrest frame 11. At the same time, the H-shaped reinforcement structure can also strengthen the structure of the seat cushion frame 21.

[0045] In addition, the seat cushion frame 21 of the embodiment of the present invention also has some other designs to enhance the structural strength of each part. For example, the seat cushion frame 21 further includes a transverse reinforcement beam 25. The transverse reinforcement beam 25 is constructed as a transverse double-arch anti-submarine beam, that is, the transverse reinforcement beam 25 includes a transverse section 252 in the middle and arched sections 251 on both sides of the transverse section 252. The transverse section 252 and the arched sections 251 are integrally formed and continuous. The arched sections 251 are arched along the height direction of the seat cushion frame 21, improving the support and bearing effect of the seat cushion frame 21 on the covering surface layer 22.

[0046] Among them, the transverse section 252 is connected to the two middle longitudinal beams of the first reinforcement structure. The two arched sections 251 are located on both sides of the first reinforcement structure and are connected to the end longitudinal beams of the seat cushion frame 21. And the bottom ends of the transverse reinforcement beam 25 are connected to the separation frame 8. The separation frame 8 is adapted to be selectively connected or separated from the locking frame. When the seat 100 is in the normal state, the separation frame 8 is connected to and locked with the locking frame 10. When the seat 100 is in the folded state, the separation frame 8 can be separated from the locking frame 10. The specific locking or separating method between the separation frame 8 and the locking frame 10 can adopt the methods commonly used by those skilled in the art, so as to fold the seat 100; that is to say, the transverse reinforcement beam 25 provided in the embodiment of the present invention can not only strengthen the seat cushion frame 21, but also ensure the strength of the connection between the bottom of the seat cushion frame 21 and the separation frame 8.

[0047] Furthermore, double flanging fixed brackets 9 are designed on both sides of the flip seat 100. The double flanging fixed brackets 9 are provided with flanges along the front-back direction of the seat 100. One side of the fixed bracket 9 is provided with a flip shaft connected to the seat cushion frame 21. The flip shaft is rotatably connected to the fixed bracket 9, and the flip shaft is driven by a power component to flip so as to drive the seat cushion 2 to flip. The double flanging fixed brackets 9 can effectively control the upward deformation of the flip shaft of the flip mechanism while installing and arranging flip function parts.

[0048] In the embodiment of the present utility model, a C-shaped reinforcing plate 214 is also provided inside the joint of the end longitudinal beam of the seat cushion frame 21 and the rear seat cross beam 211. The C-shaped reinforcing plate 214 can ensure the structural strength of the connecting joint of the seat cushion frame 21.

[0049] It should also be noted that the buckle mounting bracket 24 is installed on the bottom surface of the rear seat cross beam 211 and another middle longitudinal beam, which improves the connection strength of the buckle mounting bracket 24. The buckle 241 is installed on the upper part of the buckle mounting bracket 24 and the insertion port of the buckle 241 is exposed on the surface of the seat 100, thereby improving the connection strength of the buckle 241.

[0050] In some embodiments, the seat backrest 1 includes a backrest frame 11. The backrest frame 11 includes a first frame 111 and a second frame 112. The first frame 111 is connected to a rotating shaft 5, and the second frame 112 is connected to another rotating shaft 5. The two rotating shafts 5 are axially opposite. A connecting plate structure 6 is provided between the first frame 111 and the second frame 112. The connecting plate structure 6 is fixedly connected to the seat cushion frame 21 and rotatably connected to the corresponding rotating shaft 5.

[0051] That is to say, the first frame 111 is rotatable relative to the seat cushion 2 through a rotating shaft 5, and the second frame 112 is rotatable relative to the seat cushion 2 through another rotating shaft 5, so as to realize that the first frame 111 and the second frame 112 can rotate relative to the seat cushion 2 independently. At the connection of the two rotating shafts 5, the first frame 111 and the second frame 112 are connected through the connecting plate structure 6, and the connecting plate structure 6 is connected to the seat cushion frame 21. Compared with the way of separately arranging the connecting plate structure 6 and the seat cushion frame 21 for the first frame 111 and the second frame 112, when the first frame 111 and the second frame 112 are connected to the seat cushion frame 21, it can be more compact, occupy less space, and effectively control the upward deformation of the rear seat cross beam 211 of the seat cushion frame 21.

[0052] Specifically, refer to Figure 2As shown, each rotating shaft 5 is connected to an angle adjuster 7. The angle adjuster 7 is driven by a driving member to adjust the rotating shaft 5. The first frame 111 and the second frame 112 are respectively fixedly connected to the corresponding rotating shafts 5, and the rotating shafts 5 are rotatably connected to the connecting plate structure 6. That is, the first frame 111 and the second frame 112 can rotate relative to the seat frame 21. Thus, by adjusting the rotating shaft 5 through the angle adjuster 7, the angles of the first frame 111 and the second frame 112 can be adjusted independently.

[0053] In some embodiments, the connecting plate structure 6 includes two opposite adapter plates 62 and two opposite fixing plates 61. The two fixing plates 61 are buckled and both are connected to the seat frame 21. The two adapter plates 62 are respectively located outside the two fixing plates 61, and the two adapter plates 62 are both rotatably connected to the corresponding rotating shafts 5.

[0054] In practice, the adapter plate 62 of the connecting plate structure 6 is rotatably connected to the rotating shaft 5 and fixedly connected to the fixing plate 61, and the fixing plate 61 is fixedly connected to the seat frame 21. That is, the rotating shaft 5 can rotate relative to the seat frame 21. When the rotating shaft 5 drives the backrest frame 11 to rotate under the drive of the driving member, the adapter plate 62 does not move, and the rotating shaft 5 rotates relative to the adapter plate 62. Through the connection mode of the adapter plate 62 and the fixing plate 61, not only can the fixed connection between the connecting plate structure 6 and the seat frame 21 be realized, but also the rotational connection relationship between the connecting plate structure 6 and the backrest frame 11 can be realized, and the connecting plate structure 6 can support the backrest frame 11.

[0055] Refer to Figure 5 As shown, the two fixing plates 61 are first buckled and connected and fixedly connected to the seat frame 21, and then the two adapter plates 62 are respectively fixedly connected to the outside of the fixing plates 61. That is, there is a distance between the two adapter plates 62, which is convenient for each adapter plate 62 to be connected to the corresponding rotating shaft 5 and can also achieve a compact effect. And the two fixing plates 61 are buckled and connected, so that the structure formed after the connection of the two fixing plates 61 forms a part of the strengthening structure, and the problem of large space occupation caused by separately arranging the first frame 111 and the second frame 112 and connecting them to the seat frame 21 is avoided. That is to say, by the way of buckling and connecting the two fixing plates 61, the strength of the connection between the connecting plate structure 6 and the seat frame 21 can be improved while saving space.

[0056] In some embodiments, the seat cushion 2 of the seat is provided with three seats 23. One of the first frame 111 or the second frame 112 corresponds to two seats 23 and the other corresponds to one seat 23, and the seat belt 101 is applicable to the middle seat 23 among the three seats 23.

[0057] That is to say, for the seat 100 with three seats 23, when using the seat belt 101 at the position of the middle seat 23, one fixing point of the seat belt 101 may be located on the ceiling, and the other fixing point is located on the covering surface layer 22 of the seat cushion 2. It is not convenient to effectively protect the occupant when adjusting the angle, and the other fixing point exposed on the covering surface layer 22 makes the occupant feel uncomfortable. In the embodiment of the present invention, one fixing point of the middle seat 23 is arranged at the rear side of the backrest frame 11 of the vehicle, and the other fixed end is located at the bottom of the seat rear cross beam 211 of the seat cushion frame 21, thereby improving the comfort of the occupant.

[0058] Combined Figure 1 and Figure 2 As shown, for example, the first frame 111 corresponds to two seats 23, the second frame 112 corresponds to one seat 23, and at the same time, the retractor 117 and the guiding structure 119 are arranged on the first frame 111, so that when the seat belt 101 is pulled out from the retractor 117 and the guiding structure 119, it can protect the occupant of the middle seat 23.

[0059] In some embodiments, the backrest frame 11 includes a backrest cross beam 113 and a plurality of backrest longitudinal beams 114. A second transverse strengthening member 115 is arranged between two of the backrest longitudinal beams 114. The second transverse strengthening member 115 is parallel to the backrest cross beam 113 so that a second strengthening structure is formed between the two backrest longitudinal beams 114 and the second transverse strengthening member 115. The second strengthening structure is located on the side of the first frame 111 close to the second frame 112.

[0060] That is to say, the second strengthening structure is configured as an H-shaped structure. The H-shaped structure of the second strengthening structure is located on the side of the first frame 111 of the backrest frame 11 close to the second frame 112, and at least partially opposite to the first strengthening structure of the seat cushion frame 21, so as to strengthen the backrest frame 11 corresponding to the middle seat 23, and the second strengthening structure can reduce the longitudinal and transverse deformation of the first frame 111 and improve the overall strength.

[0061] Referring to Figure 2As shown, the first frame 111 is provided with three backrest longitudinal beams 114, one of which is located in the middle, and the second frame 112 is provided with two backrest longitudinal beams 114. A second transverse reinforcement 115 is welded between the backrest longitudinal beam 114 in the middle of the first frame 111 and the backrest longitudinal beam 114 located at the end, so that an H-shaped structure can be formed between the backrest longitudinal beam 114 in the middle and the backrest longitudinal beam 114 at one end, thereby strengthening the first frame 111. The backrest crossbeam 113 of the backrest frame 11 includes a top crossbeam and a bottom crossbeam, wherein the retractor bracket 118 is connected to the backrest longitudinal beam 114 in the middle of the first frame 111 and the bottom crossbeam of the first frame 111 by bolts to improve the connection strength of the retractor bracket 118, that is, to improve the connection reliability of the retractor 117. At the same time, the frame of the first frame 111 is larger than the frame of the second frame 112, that is, the H-shaped structure formed between the backrest longitudinal beam 114 in the middle of the first frame 111 and the backrest longitudinal beam 114 at one end can avoid the lateral and longitudinal deformation of the first frame 111.

[0062] In addition, a guide structure 119 is provided at the top backrest cross beam 113, so that the safety belt 101 pulled out by the retractor 117 can extend upward along the lower part of the backrest frame 11 and reach the position of the guide structure 119 to extend out. The guide structure 119 is provided with a detachable guide cover 1191, and the guide cover 1191 is provided with a guide hole. The safety belt 101 extends out through the guide hole, thereby improving the guiding effect on the extension direction of the safety belt 101.

[0063] It should be noted that a third reinforcing structure 1131 is also provided on the outside of the top crossbeam of the backrest crossbeam 113, and a vertical headrest sleeve 1132 is connected inside the top crossbeam. The headrest sleeve 1132 is used to install a headrest, and the third reinforcing structure 1131 is arranged around the top crossbeam and avoids the headrest sleeve 1132; if the top crossbeam is constructed as a square tube or a round tube, the third reinforcing structure 1131 is constructed as a C-shaped reinforcing structure, and the C-shaped reinforcing structure is welded to the outer periphery of the top crossbeam, which improves the strength of the top crossbeam and also improves the strength of the headrest sleeve 1132 connected to the top crossbeam, so that the top crossbeam has a better supporting effect on the headrest sleeve 1132.

[0064] The present utility model also discloses a vehicle, which includes the above-mentioned seat 100. One end of the seat belt 101 extends from the retractor 117 and the other end is fixedly connected to the bottom of the seat cushion frame 21. The buckle 102 in the middle of the seat belt 101 is further connected to the buckle 241 of the seat cushion frame 21, thereby forming a three-point fixation. That is to say, first, the seat belt 101 is arranged on the seat 100 instead of on the ceiling, solving the problem that when the seat backrest 1 is adjusted at a large angle, the human body is far away from the seat belt 101 and the seat belt cannot play a protective role. In addition, the lower fixing point of the seat belt 101 is located at the bottom of the seat cushion frame 21, preventing the lower fixing point of the seat belt 101 from being arranged on the seat cushion surface and causing a foreign body sensation on the surface. In addition, the strength of the entire seat cushion frame 21 and the backrest frame 11 is designed, enhancing the strength of each important position of the seat cushion frame 21 and the backrest frame 11, thereby improving the experience of the occupants.
