[Figure 7] FIG. 7 is a schematic diagram for explaining the operating angles of the first recliner 5 and the second recliner provided on the seat 91. As shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] One embodiment of the vehicle seat of the present invention will be described with reference to a seat 91. For ease of explanation, the up / down, front / rear, left / right directions are defined by arrows shown in FIG.

[0010] 1 is a perspective view of a bench seat ST including vehicle seats 91 and 92, seen from diagonally above the left front. Each of the seats 91 and 92 can accommodate one adult passenger, and each of the seats can be arranged into first to fourth configurations, which will be described later. The bench seat ST is installed in a passenger compartment of a vehicle. In this example, the vehicle is an automobile, and is installed on a floor FL as a rear seat of, for example, a station wagon.

[0011] Since seats 91 and 92 have the same configuration and are symmetrical on the left and right, the seat 91 installed on the left side will be described as a representative example with reference to Figs. 1 and 2. The seat 91 includes a seat cushion 1, a seat back 2, a bottom frame unit 3, a rail base 4, a first recliner 5, a second recliner 6, and a cover 8.

[0012] 2, the rail base 4 has a fixed rail 43, and a first leg 41 and a second leg 42 attached to the underside of the fixed rail 43 and spaced apart in the front-rear direction. A pair of rail bases 4 are provided spaced apart on the left and right sides of the seat 91. Specifically, the rail base 4 is fixed to the floor FL of the vehicle by bolts (not shown) or the like so that the first leg 41 and the second leg 42 are oriented such that the fixed rail 43 extends in the front-rear direction.

[0013] The bottom frame unit 3 has a base frame 31, a seat cushion bracket 32, and a seat back bracket 33 shown in FIG. 2, and a cushion side bracket 34 and a back side bracket 35 shown in FIG. The base frame 31 is a pipe member formed into a rectangular frame shape that is placed on a pair of fixed rails 43. Sliders 311, 312 that slidably engage with the fixed rails 43 are fixed to the lower parts of a pair of left and right frame parts extending in the front-rear direction of the base frame 31 and spaced apart in the front-rear direction. This allows the bottom frame unit 3 to slide in the front-rear direction on the fixed rail 43. In addition, the bottom frame unit 3 can be locked at any position on the fixed rail 43 by a locking mechanism (not shown). The bottom frame unit 3 may be integrated with the rail base 4 and not slide.

[0014] The seat cushion bracket 32 ​​and the seat back bracket 33 are fixed to the front and rear parts of the left frame part of the base frame 31 in an upwardly extending position. A first recliner 5 is fixed to an upper portion of the seat cushion bracket 32 ​​about an axis line CL1 which is a first axis line extending in the left-right direction. A second recliner 6 is fixed to an upper portion of the seatback bracket 33 about an axis line CL2 which is a second axis line extending laterally. The cushion side bracket 34 and the back side bracket 35 shown in FIG. 1 are fixed to the front and rear parts, respectively, of the right frame part of the base frame 31 in an upwardly rising position.

[0015] In order to maintain the appearance quality, the first recliner 5 and the seat cushion bracket 32, the second recliner 6 and the seat back bracket 33, and the left side of the bottom frame unit 3 are covered with a resin cover 8 as shown in Figure 1 so as not to be visible from the outside.

[0016] The seat cushion 1 has a seat cushion frame 11 and a cushion pad 12. The seat cushion frame 11 is a rectangular frame-shaped pipe member that extends roughly in the front-rear and left-right directions as shown in Fig. 1. As shown in Fig. 2, the left side of the base part of the seat cushion frame 11 is rotatably supported by the first recliner 5 (see arrow DR1 in Fig. 2), and the right side of the base part is rotatably supported by the cushion side bracket 34 shown in Fig. 1. This allows the seat cushion 1 to perform a reclining action including a lock based on the specifications of the first recliner 5.

[0017] The cushion pad 12 is a thick plate-like member having compressive elasticity, which is formed to accommodate the seat cushion frame 11 as a core material therein and cover it. The cushion pad 12 is formed, for example, by wrapping a sponge material with a resin skin member. 2, when the seat cushion 1 is rotated about the axis CL1 and raised, the surface that becomes the front side is the first surface 12a and the surface that becomes the rear side is the second surface 12b. The cushion pad 12 is formed so that the first surface 12a and the second surface 12b are substantially parallel surfaces. In the seat cushion 1, the direction in which the axis CL1 extends is the width direction, and the extension direction perpendicular to the width direction (the direction connecting the base and the tip) is the vertical direction.

[0018] The seat back 2 has a seat back frame 21 and a back pad 22. The seat back frame 21 is a rectangular frame-shaped pipe member that extends generally in the left-right, diagonal, and up-down directions in the upright state shown in Fig. 1. As shown in Fig. 2, the left side of the base part of the seat back frame 21 is rotatably supported by the second recliner 6 (see arrows DR21 and DR22 in Fig. 2), and the right side of the base part is rotatably supported by the back side bracket 35 shown in Fig. 1. As a result, the seat back 2 performs a reclining action including a lock based on the specifications of the second recliner 6.

[0019] The back pad 22 is a thick plate-like member having compressive elasticity, which is formed to accommodate the seat back frame 21 as a core material therein and cover it. The back pad 22 is formed, for example, by wrapping a sponge material with a resin skin member. 2, when the seat back 2 is rotated about the axis CL2 and raised, the front surface is the first surface 22a and the rear surface is the second surface 22b. The back pad 22 is formed so that the first surface 22a and the second surface 22b are substantially parallel to each other. In the seat back 2, the direction in which the axis CL2 extends is the width direction, and the extension direction perpendicular to the width direction (the direction connecting the base and the tip) is the vertical direction.

[0020] The first recliner 5 has a first lever 59 that extends rearward from the cover 8 and is exposed to the outside. When an occupant or the like operates the first lever 59, the lock for the reclining operation of the seat cushion 1 can be released. The second recliner 6 has a second lever 69 that extends forward from the cover 8 and is exposed to the outside. By operating the second lever 69 by an occupant or the like, the lock for the reclining operation of the seat back 2 can be released.

[0021] As described above, in the seat 91, the seat cushion 1 is connected to the first recliner 5 and can recline around the axis line CL1, and the seat back 2 is connected to the second recliner 6 and can recline around the axis line CL2. As a result, the seat 91 can be arranged in any of the first to fourth modes described below with reference to FIGS.

[0022] (First embodiment: see FIG. 3) The first mode is a seat mode in which an occupant sits facing forward. Specifically, the seat cushion 1 in the first mode is at the end position of the rotation stroke most clockwise in FIG. 3, and the first surface 12a of the cushion pad 12 is a surface that is inclined downward as it moves away from the axis CL1 by an angle θc4 clockwise with respect to the horizontal plane LH. On the other hand, the seat back 2 in the first mode is a surface inclined clockwise with respect to the vertical plane LV by an angle θbN. The angles θc4 and θbN are set so that an ordinary adult sits in a natural sitting position when sitting facing forward.

[0023] The angular position of the seat cushion 1 in this first state is defined as angular position PC4, and the angular position of the seat back 2 is defined as angular position BN. When the seat back 2 rotates to reach angular position BN, it is automatically locked by the action of the second recliner 6. The lock is released by operating the second lever 69. Although the seat cushion 1 is not locked at angular position PC4, clockwise rotation is restricted. This is because the first state is a state in which the occupant sits facing forward, and the seat cushion 1 is normally pressed downward by the occupant's buttocks. This first embodiment is also referred to as the first sheet embodiment.

[0024] (Second embodiment: see FIG. 4) The second mode is a seat mode in which the occupant sits facing backward. Specifically, the seat cushion 1 in the second mode is at the most counterclockwise end position of the rotation stroke in FIG. 4, and the second surface 12b of the cushion pad 12 is inclined counterclockwise by an angle θc2 with respect to the vertical plane LV. On the other hand, the seat back 2 in the second mode is at the most counterclockwise end position of the rotation stroke in FIG. 4, and the second surface 22b of the back pad 22 is in a horizontal position that coincides with the horizontal plane LH.

[0025] The angular position of the seat cushion 1 in this second mode is defined as angular position PC2, and the angular position of the seat back 2 is defined as angular position PB3. When the seat cushion 1 reaches angular position PC2, it is automatically locked by the action of the first recliner 5, and the lock is released by operating the first lever 59. When the seat back 2 rotates counterclockwise and reaches angular position PB3, it is automatically locked by the action of the second recliner 6. In addition, the lock is released by operating the second lever 69. The rearward-facing seating possible in the second position is a simple seating position because the second surface 22b of the seat back 2 becomes a horizontal seating surface; however, when used in a wagon, the seating position faces the luggage compartment and hatchback door, making it highly convenient. In addition, since the second surface 22b of the seat back 2 is horizontal, the seat back 2 can also be used as a table for placing beverages and the like. This second embodiment is also referred to as the second sheet embodiment.

[0026] (Third embodiment: see FIG. 5) In the third position, the first surface 12a of the seat cushion 1 is horizontal with respect to the first position, and the seat back 2 is in the same angular position BN as in the first position. This angular position of the seat cushion 1 is designated as angular position PC3. The seat cushion 1 is automatically locked at angular position PC3 by the action of the first recliner 5, and the lock is released by operating the first lever 59. The seat back 2 is in the same angular position BN as in the first position. In other words, this is a position in which the second position of sitting facing backwards is converted to sitting facing forwards.

[0027] In the first embodiment, the seat cushion 1 is inclined so that it becomes lower towards the back (rear), making it a special embodiment for sitting that places less strain on the body even when sitting for long periods of time. In contrast, the third embodiment is similar to the second embodiment for sitting, but provides a horizontal surface on which items such as beverages can be placed in a horizontal position, allowing the seat cushion 1 to be used as a table.

[0028] (Fourth embodiment: see FIG. 6) In the fourth mode, the seat cushion 1 is tilted backward with respect to the first mode so that the first surface 12a is horizontal, and the seat back 2 is also tilted backward with the first surface 22a being horizontal. This angular position of the seat cushion 1 is the above-mentioned angular position PC3, and this angular position of the seat back 2 is the above-mentioned angular position PB2.

[0029] The seat 91 is designed so that the first surface 12a and the first surface 22a are positioned on approximately one plane when the seat cushion 1 and the seat back 2 are laid horizontally backward. As a result, the first surface 12a and the first surface 22a form a substantially continuous horizontal plane SH, and the seat 91 can be used as a bed inside the station wagon. Here, the bed in the seat arrangement means a state in which a generally horizontal and substantially continuous plane is formed by the seat cushion 1 and the seat back 2. This fourth mode is also called the bed mode.

[0030] The first recliner 5 and the second recliner 6 may have a known structure and are set in advance to operate as shown in Fig. 7. Fig. 7 is a schematic diagram for explaining the operating mode of the first recliner 5 and the second recliner provided on the seat 91.

[0031] The angular positions PC4, PC2L, and PC3L of the first recliner 5 in FIG. 7 correspond to the angular positions PC4, PC2, and PC3 of the seat cushion 1 in the first to fourth modes, respectively. The angular positions BNL, PB3L, and PB2L of the second recliner 6 in FIG. 7 correspond to the angular positions BN, PB3, and PB2 of the seat back 2 in the first to fourth modes, respectively.

[0032] 7 indicates that the automatic lock is activated at that position. Moreover, the angular position PC1 indicates the reference position of the first recliner 5, and the angular position PB1 indicates the reference position of the second recliner 6. 7 is a schematic diagram showing the operating state of the first recliner 5 and the second recliner 6 alone, and therefore does not match the angles of the first to fourth states of the seat cushion 1 and the seat back 2. For example, the angle position PC4 of the first recliner 5 is shown as non-horizontal, but when attached to the seat 91, the first surface 12a of the seat cushion 1 is horizontal at the angle position PC4.

[0033] As shown in FIG. 7, when the seat cushion 1 is between angular positions PC3L and PC1, if the first lever 59 is operated to release the lock in the absence of external force, the first recliner 5 will naturally return to the reference position, angular position PC1 (see DR52). Furthermore, when a clockwise force is applied to the seat cushion 1, which is in the angular position PC1, to rotate it to the angular position PC3L (arrow DR50), automatic locking is effected and the angular position is maintained at PC3L. Furthermore, when the lock is released and the lock lever is rotated clockwise from the angular position PC3L (arrow DR53), the lock lever is maintained at the position where the rotation was stopped due to the frictional force and does not return to its original position naturally. The clockwise rotation end is the angular position PC4, and the lock lever can be rotated up to the angular position PC4.

[0034] On the other hand, the first recliner 5 generates a resistance force (a force in the clockwise direction) when it rotates counterclockwise from the angular position PC1, which is the reference position. The seat cushion 1 rotates counterclockwise by applying a counterclockwise force against the resistance force, and when it reaches the angular position CNL, it is automatically locked and maintained in that position (arrow DR54). When the first lever 59 is operated to release the lock at the angular position CNL, the resistance force causes it to return to angular position PC1 (DR51). When the first lever 59 is operated to release the lock at the angular position CNL and a counterclockwise force is applied against the resistance force to reach angular position PC2L, automatic locking is activated and the position is maintained (arrow DR55). When the lock is released at angular position PC2L, the resistance force causes it to naturally return to angular position PC1 (arrow DR56).

[0035] When the seat back 2 is between angle position PB3L and angle position PB1, if the second lever 69 is operated to release the lock in the absence of any external force, the second recliner 6 will naturally return to the reference position, angle position PB1 (see arrow DR62). 7 is applied to the seat back 2 from the angle position PB1 to rotate it to the angle position PB3L (arrow DR60), the seat back 2 is automatically locked and maintained at the angle position PB3L. In the second recliner 6, the angle position PB3L is the position where the seat back 2 is rotated the furthest counterclockwise.

[0036] On the other hand, there is a resistance force (counterclockwise force) against clockwise rotation from the reference position, angular position PB1, and when a clockwise force against that resistance is applied to the seat back 2 to rotate it and reach angular position BNL, an automatic lock is activated and the position is maintained (arrow DR64). When the second lever 69 is operated to release the lock at the angular position BNL, the resistance force causes the lever to return to angular position PB1 (DR61). When the second lever 69 is operated to release the lock at the angular position BNL and a clockwise force is applied against the resistance force until the angular position PB2L is reached, automatic locking is activated and the lever is maintained in that position (arrow DR65). When the lock is released at the angular position PB2L, the resistance force causes the lever to return to angular position PB1 (arrow DR66).

[0037] By mounting the first recliner 5 and second recliner 6 that operate as described above, the seat 91 can be converted from the first position shown in Figure 3 to second to fourth positions, for example, in the following manner.

[0038] (From the first embodiment to the second embodiment: see Figs. 3, 4, and 7) The first lever 59 is operated to unlock the seat cushion 1 from the angular position PC4. The seat cushion 1 naturally returns from the angular position PC4 to the angular position PC1 (FIG. 7). From the angular position PC1, a counterclockwise force against the resistance force is applied to the seat cushion 1 to rotate it to the angular position PC2. The seat cushion 1 is automatically locked when it reaches the angular position PC2.

[0039] Next, the second lever 69 is operated to unlock the seat back 2 from the angle position BN. The seat back 2 naturally returns from the angle position BN to the angle position PB1 (FIG. 7). From the angle position PB1, a counterclockwise force is applied to the seat back 2 to rotate it to the angle position PB3. When the seat back 2 reaches the angle position PB3, it is automatically locked. This places the seat 91 in the second position.

[0040] (From the second embodiment to the third embodiment: see Figs. 4, 5, and 7) The second lever 69 is operated to unlock the seat back 2 from the angle position PB3. The seat back 2 naturally returns from the angle position PB3 to the angle position PB1 (FIG. 7). From the angle position PB1, a clockwise force is applied to the seat back 2 to rotate it to the angle position BN. The seat back 2 is automatically locked when it reaches the angle position BN.

[0041] Next, the first lever 59 is operated to unlock the seat cushion 1 from the angular position PC2, and a clockwise force is applied to the seat cushion 1 to rotate it clockwise to the angular position PC3. The seat cushion 1 is automatically locked when it reaches the angular position PC3. This places the seat 91 in the third position.

[0042] (From the third embodiment to the fourth embodiment: see Figs. 5 to 7) The second lever 69 is operated to unlock the seat back 2 from the angular position BN, and a force is applied to the seat back 2 in the clockwise direction in FIG. 5 to rotate it to the angular position PB2. The seat back 2 is automatically locked when it reaches the angular position PB2. This places the seat 91 in the fourth position.

[0043] As described above, the seat 91 includes the first recliner 5 that reclines the seat cushion 1 and the second recliner 6 that reclines the seat back 2. The first recliner 5 and the second recliner 6 can be changed in the seat arrangement of the seat cushion 1 and the seat back 2 to a first state in which the occupant can be seated in a first orientation (facing forward), a second state in which the occupant can be seated in a second orientation (facing backward) opposite to the first orientation, a third state in which the occupant can be seated facing forward and the seat cushion 1 can be used as a table, and a fourth state in which the first surface 12a of the seat cushion 1 and the first surface 22a of the seat back 2 are positioned on the same plane and the seat can be used as a bed having a wide horizontal plane SH.

[0044] In this way, the seat 91, which is a vehicle seat, can be arranged in a variety of ways, including as a bed according to the fourth embodiment.

[0045] Like the seat 91, the seat 92 can also be transformed between the first to fourth positions independently of the seat 91. Therefore, the bench seat ST can convert either or both of the seat 91 and the seat 92 into a bed.

[0046] The present invention is not limited to the above-described embodiment and procedure, and various modifications are possible without departing from the gist of the present invention.

[0047] The vehicle is not limited to an automobile, but may be, for example, a railroad car, an aircraft, a ship, an airship, or a drone. The seat 91 may be installed in the vehicle with the axis lines CL1 and CL2 extending in the left-right direction, but the present invention is not limited to this. The seat 91 may be installed in the vehicle with the axis lines CL1 and CL2 extending in the front-rear direction or in an oblique direction.

[0048] The seat 91 is not limited to the first recliner 5 and the second recliner 6 being attached to the same side in the width direction (the above-mentioned left side). The seat 91 may be a single unit that is not combined with the seat 92, and one of the first recliner 5 and the second recliner 6 may be attached to one side in the width direction and the other to the other side in the width direction.

[0049] The first surface 12a of the seat cushion 1 and the first surface 22a of the seat back 2 do not have to be completely flat. For example, the vicinity of any of the seat cushion bracket 32, the seat back bracket 33, the cushion side bracket 34, and the back side bracket 35 may be raised.
