[0067] A mode of the vehicle seat of the present invention is described using the seat 91. Figure 1 The arrows shown define the directions up, down, front, back, left, and right.

[0068] Figure 1 This is a perspective view of a long seat ST viewed from the upper left front obliquely, and the long seat ST is configured to include a seat 91 and a seat 92 as a vehicle seat. The seat 91 and the seat 92 can each seat an adult passenger, and can provide the seat configurations of the first to fourth modes described below.

[0069] The bench seat ST is provided in a vehicle compartment. In this example, the vehicle is a car, and the bench seat ST is provided on the floor FL as a rear seat of a station wagon, for example.

[0070] Since the seat 91 and the seat 92 have the same structure that is bilaterally symmetrical, as a representative, refer to Figure 1 and Figure 2 The seat 91 provided on the left side will be described.

[0071] 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 .

[0072] like Figure 2 As shown, the rail base 4 has a fixed rail 43 and a first leg 41 and a second leg 42 mounted on the lower surface of the fixed rail 43 in a manner separated in the front-rear direction. For the seat 91, a pair of rail bases 4 are provided in a manner separated from each other on the left and right. Specifically, the rail base 4 fixes the first leg 41 and the second leg 42 to the floor FL of the vehicle by bolts (not shown) and the like in such a manner that the fixed rail 43 is in a posture extending in the front-rear direction.

[0073] The bottom frame unit 3 has Figure 2 The base frame 31, the seat cushion bracket 32 ​​and the seat back bracket 33 are shown. Figure 1 The seat cushion side bracket 34 and the seat back side bracket 35 are shown.

[0074] The base frame 31 is a rectangular frame-shaped pipe member mounted on a pair of fixed rails 43. Sliders 311 and 312 slidably engaged with the fixed rails 43 are fixed to the lower part of a pair of left and right frame parts extending forward and backward in the base frame 31 in a manner separated in the forward and backward direction.

[0075] Thereby, the bottom frame unit 3 can slide in the front-rear direction on the fixed rail 43. In addition, the bottom frame unit 3 is locked at an arbitrary position on the fixed rail 43 by a locking mechanism (not shown).

[0076] The bottom frame unit 3 may be integrated with the rail base 4 so as not to slide.

[0077] The seat cushion bracket 32 ​​and the seat back bracket 33 are fixed to the front and rear portions of the left frame portion of the base frame 31 in an upwardly upright posture.

[0078] The first recliner 5 is fixed to an upper portion of the seat cushion bracket 32 ​​about an axis CL1 which is a first axis extending horizontally.

[0079] The second recliner 6 is fixed to the upper portion of the seat back bracket 33 about an axis CL2 which is a second axis extending in the left-right direction.

[0080] Figure 1 The seat cushion side bracket 34 and the seat back side bracket 35 shown are fixed to the front and rear portions of the frame portion on the right side of the base frame 31 in an upwardly upright posture, respectively.

[0081] In order to maintain the appearance of taste, such as Figure 1 As shown, the first recliner 5 and the seat cushion bracket 32 ​​, the second recliner 6 and the seat back bracket 33 , and the left side portion of the bottom frame unit 3 are covered by a resin cover 8 and cannot be viewed from the outside.

[0082] The seat cushion 1 comprises a seat cushion frame 11 and a seat cushion 12. Figure 1 As shown in FIG. 1 , the seat cushion frame 11 is a rectangular frame-shaped pipe member extending in the front, rear, left, and right directions. Figure 2 As shown, in the seat cushion frame 11, the left side of the root portion is rotatably supported by the first recliner 5 (see Figure 2 The right side of the root portion is rotatably supported by the arrow DR1). Figure 1 The seat cushion side bracket 34 is shown. As a result, the seat cushion 1 performs a reclining action (reclining) including locking according to the specifications of the first recliner 5.

[0083] The seat cushion 12 is a thick plate-shaped member having compression elasticity, which is formed so as to cover the seat cushion frame 11 as a core material. The seat cushion 12 is formed by covering a sponge material with a resin skin member, for example.

[0084] like Figure 2 As shown, when the seat cushion 1 is rotated around the axis CL1 and erected, the surface on the front side is set as the first surface 12a, and the surface on the rear side is set as the second surface 12b. The seat cushion 12 is formed in such a way that the first surface 12a and the second surface 12b are substantially parallel. In the seat cushion 1, the extending direction of the axis CL1 is the width direction, and the extending direction orthogonal to the width direction (the direction connecting the root and the front end) is the longitudinal direction.

[0085] The seat back 2 has a seat back frame 21 and a cushion 22. The seat back frame 21 is Figure 1 The pipe member is a rectangular frame-shaped pipe member that extends approximately in the left and right oblique upward and downward directions in the erected state shown. Figure 2 As shown, in the seat back frame 21, the left side of the root portion is rotatably supported by the second recliner 6 (see Figure 2 The right side of the root portion is rotatably supported by the arrows DR21 and DR22. Figure 1 The seat back side bracket 35 is shown. As a result, the seat back 2 performs a reclining action (reclining) including locking according to the specifications of the second recliner 6.

[0086] The back cushion 22 is a thick plate-shaped member having compression elasticity, which is formed so as to cover the seat back frame 21 as a core material. The back cushion 22 is formed by covering a sponge material with a resin skin member, for example.

[0087] like Figure 2 As shown, the surface on the front side when the chair back 2 is rotated around the axis CL2 and erected is set as the first surface 22a, and the surface on the rear side is set as the second surface 22b. The cushion 22 is formed in such a way that the first surface 22a and the second surface 22b are substantially parallel surfaces. In the chair back 2, the extending direction of the axis CL2 is the width direction, and the extending direction orthogonal to the width direction (the direction connecting the root and the front end) is the longitudinal direction.

[0088] The first recliner 5 includes a first rod 59 that extends rearward from the cover 8 and is exposed to the outside. The occupant or the like can unlock the seat cushion 1 during the tilting operation by operating the first rod 59.

[0089] The second recliner 6 includes a second rod 69 that extends forward from the cover 8 and is exposed to the outside. The seat back 2 can be unlocked during the tilting operation by the passenger or the like operating the second rod 69.

[0090] As described above, in the seat 91 , the seat cushion 1 is connected to the first recliner 5 and tilts around the axis CL1 , and the seat back 2 is connected to the second recliner 6 and tilts around the axis CL2 .

[0091] Thus, the seat 91 can achieve the following by seat configuration. Figure 3 to Figure 6 The first to fourth aspects will be described.

[0092] (First form: see Figure 3 )

[0093] The first state is a seat state in which the occupant sits forward. Specifically, the seat cushion 1 in the first state is in the rotation stroke. Figure 3 At the end position where the seat cushion 12 is rotated clockwise to the maximum extent, the first surface 12a of the seat cushion 12 is rotated clockwise by an angle θc4 relative to the horizontal plane LH, and becomes an inclined surface that faces downward as it moves away from the axis CL1. On the other hand, in the seat back 2 in the first state, the first surface 22a of the back cushion 22 becomes an inclined surface that is rotated clockwise by an angle θbN relative to the vertical plane LV. The angle θc4 and the angle θbN are set so that an average adult can take a natural sitting posture when sitting forward.

[0094] The angular position of the seat cushion 1 in the first state is set to the angular position PC4, and the angular position of the seat back 2 is set to the angular position BN. When the seat back 2 rotates and reaches the angular position BN, 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 seat cushion 1 is in a state where it is not locked but is restricted from rotating clockwise at the angular position PC4. This is because the first state is a state of sitting forward, and the seat cushion 1 is usually pressed downward by the buttocks of the occupant.

[0095] This first state is also referred to as a first seat state.

[0096] (Second form: see Figure 4 )

[0097] The second state is a state in which the occupant sits backward. Specifically, the seat cushion 1 in the second state is in the rotation stroke. Figure 4 At the end position where the seat cushion 12 is rotated counterclockwise to the maximum extent, the second surface 12b of the seat cushion 12 becomes an inclined surface rotated counterclockwise by an angle θc2 relative to the vertical plane LV. Figure 4 At the end position where the counterclockwise rotation is performed to the greatest extent, the second surface 22b of the cushion 22 is in a horizontal posture that is consistent with the horizontal plane LH.

[0098] The angular position of the seat cushion 1 in the second state is set to the angular position PC2, and the angular position of the seat back 2 is set to the angular position PB3. When the seat cushion 1 reaches the angular position PC2, it is automatically locked by the action of the first recliner 5, and the lock is released by operating the first rod 59. When the seat back 2 rotates counterclockwise and reaches the 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 rod 69.

[0099] As for the rearward sitting that can be achieved in the second state, since the second surface 22b of the seat back 2 is a horizontal seating surface, although this rearward sitting is a simple seating state, it is convenient to sit facing the trunk and hatchback tailgate during the use of the station wagon.

[0100] Furthermore, since the second surface 22 b of the seat back 2 is horizontal, the seat back 2 can also be used as a table for placing drinks and the like.

[0101] This second state is also referred to as a second seat state.

[0102] (Third form: see Figure 5 )

[0103] The third state is a state in which the first surface 12a of the seat cushion 1 becomes horizontal relative to the first state, and the seat back 2 is in the same angular position BN as in the first state. This angular position of the seat cushion 1 is set as the angular position PC3. The seat cushion 1 is automatically locked at the 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 state. That is, the second state of sitting backward is transformed into the state of sitting forward.

[0104] In the first state, the seat cushion 1 is inclined so that it becomes lower toward the deep side (rear side), and is a state dedicated to sitting with less burden even for a long time. In contrast, the third state is the same as the second state for sitting, but on the other hand, since a horizontal surface can be obtained, drinks and other items can be placed in a horizontal state, and the seat cushion 1 can be used as a table.

[0105] (The fourth form: see Figure 6 )

[0106] The fourth state is a state in which the seat cushion 1 is folded backward to make the first surface 12a horizontal, and the seat back 2 is folded backward to make the first surface 22a horizontal. The angular position of the seat cushion 1 is the aforementioned angular position PC3, and the angular position of the seat back 2 is the angular position PB2.

[0107] In the seat 91, when the seat cushion 1 and the seat back 2 are horizontally folded backward, the first surface 12a and the first surface 22a are approximately located on the same plane. Thus, the first surface 12a and the first surface 22a form a substantially continuous horizontal plane SH, which can be used as a bed inside the travel vehicle.

[0108] Here, the bed position in the seat arrangement means a state in which a substantially horizontal and substantially continuous plane is formed by the seat cushion 1 and the seat back 2. This fourth state is also referred to as a bed position state.

[0109] The first recliner 5 and the second recliner 6 can be constructed using known structures. Figure 7 The actions shown are each set in advance. Figure 7 It is a schematic diagram for explaining the operation modes of the first recliner 5 and the second recliner included in the seat 91 .

[0110] Figure 7 The angular positions PC4, PC2L, and PC3L of the first recliner 5 in FIG. 5 correspond to the angular positions PC4, PC2, and PC3 of the seat cushion 1 in the first to fourth states, respectively.

[0111] Figure 7 The angular positions BNL, PB3L, and PB2L of the second recliner 6 in FIG. 6 correspond to the angular positions BN, PB3, and PB2 of the seat back 2 in the first to fourth states, respectively.

[0112] Figure 7 The "L" at the end of the symbol in means that the automatic lock is applied at this position. In addition, the angle position PC1 indicates the reference position of the first recliner 5 , and the angle position PB1 indicates the reference position of the second recliner 6 .

[0113] Figure 7 Since the schematic diagram shows the operation state of the first recliner 5 and the second recliner 6 alone, the angles are inconsistent with the first to fourth states of the seat cushion 1 and the seat back 2. For example, although the angle position PC3L of the first recliner 5 is shown in a non-horizontal manner, when the seat 91 is installed, at the angle position PC3, the first surface 12a of the seat cushion 1 is horizontal.

[0114] like Figure 7 As shown, when the seat cushion 1 is located between the angle position PC3L and the angle position PC1, if the first lever 59 is operated to release the lock without external force, the first recliner 5 naturally returns to the angle position PC1 which is the reference position (see DR52).

[0115] Furthermore, when a clockwise force is applied to the seat cushion 1 at the angular position PC1 to rotate it to the angular position PC3L (arrow DR50 ), the seat cushion 1 is automatically locked to be maintained at the angular position PC3L.

[0116] If the lock is unlocked and the lock is unlocked, the lock is rotated clockwise (arrow DR53), friction force is applied and the lock does not return to its original position, but is maintained at a position where the lock is blocked. The end of the clockwise rotation is the angle position PC4, and the lock can be rotated to the angle position PC4.

[0117] On the other hand, the first recliner 5 generates resistance (clockwise force) when it rotates counterclockwise from the angular position PC1 as the reference position. When the seat cushion 1 is rotated counterclockwise by applying a counterclockwise force against the resistance and reaches the angular position CNL, the seat cushion 1 is automatically locked and maintained at the position (arrow DR54).

[0118] If the first rod 59 is operated to unlock at the angle position CNL, it will return to the angle position PC1 (DR51) under the action of resistance. In addition, if the first rod 59 is operated to unlock at the angle position CNL, and further resists the resistance and applies a counterclockwise force to reach the angle position PC2L, the automatic lock is applied and maintained at this position (arrow DR55). If the lock is unlocked at the angle position PC2L, it will naturally return to the angle position PC1 under the action of resistance (arrow DR56).

[0119] When the seat back 2 is located between the angular position PB3L and the angular position PB1, if the second lever 69 is operated to release the lock without an external force, the second recliner 6 naturally returns to the angular position PB1 which is the reference position (see arrow DR62).

[0120] Furthermore, if the seat back 2 at the angle position PB1 is given Figure 7 If the counterclockwise force is applied to rotate the second recliner 6 to the angle position PB3L (arrow DR60), the automatic lock is applied to maintain the angle position PB3L. In the second recliner 6, the angle position PB3L is the position where the second recliner 6 is rotated to the maximum counterclockwise direction.

[0121] On the other hand, clockwise rotation from the reference angular position PB1 generates resistance (counterclockwise force). If a clockwise force is applied to the seat back 2 to resist the resistance and rotate it to the angular position BNL, the automatic lock is applied to maintain the position (arrow DR64).

[0122] If the second rod 69 is operated to unlock at the angle position BNL, it returns to the angle position PB1 (DR61) under the action of resistance. In addition, if the second rod 69 is operated to unlock at the angle position BNL, and further resists the resistance and applies a clockwise force to reach the angle position PB2L, the automatic lock is applied and maintained at this position (arrow DR65). If the lock is unlocked at the angle position PB2L, it returns to the angle position PB1 under the action of resistance (arrow DR66).

[0123] The seat 91 is equipped with the first recliner 5 and the second recliner 6 that perform the above-mentioned operation, so that Figure 3 The first state shown is used as a reference, and state conversion is performed from the first state to the second to fourth states by, for example, the following method.

[0124] (From the first form to the second form: see Figure 3 , Figure 4 and Figure 7 )

[0125] The first lever 59 is operated to release the lock of the seat cushion 1 at the angle position PC4. The seat cushion 1 naturally returns from the angle position PC4 to the angle position PC1 ( Figure 7 ). A counterclockwise force is applied to the seat cushion 1 from the angle position PC1 to resist the resistance and rotate it to the angle position PC2. When the seat cushion 1 reaches the angle position PC2, it is automatically locked.

[0126] Next, the second lever 69 is operated to release the lock of the seat back 2 at the angular position BN. The seat back 2 naturally returns from the angular position BN to the angular position PB1 ( Figure 7 ). A counterclockwise force is applied to the seat back 2 from the angle position PB1 to rotate it toward the angle position PB3. When the seat back 2 reaches the angle position PB3, it is automatically locked. Thus, the seat 91 is changed to the second state.

[0127] (From the 2nd to the 3rd form: see Figure 4 , Figure 5 and Figure 7 )

[0128] The second lever 69 is operated to release the lock of the seat back 2 at the angle position PB3. The seat back 2 naturally returns to the angle position PB1 from the angle position PB3 ( Figure 7 ). A clockwise force is applied to the seat back 2 from the angle position PB1 to rotate it toward the angle position BN. When the seat back 2 reaches the angle position BN, it is automatically locked.

[0129] Next, the first lever 59 is operated to unlock the seat cushion 1 at the angle position PC2, and a clockwise force is applied to the seat cushion 1 to rotate it clockwise to reach the angle position PC3. When the seat cushion 1 reaches the angle position PC3, it is automatically locked. Thus, the seat 91 is changed to the third state.

[0130] (From the 3rd to the 4th state: see Figure 5 to Figure 7 )

[0131] The second lever 69 is operated to release the lock of the seat back 2 at the angle position BN, and to apply the lock to the seat back 2. Figure 5 The seat back 2 is automatically locked when it reaches the angular position PB2. Thus, the seat 91 is in the fourth state.

[0132] As described above, the seat 91 includes the first recliner 5 for tilting the seat cushion 1 and the second recliner 6 for tilting the seat back 2. The first recliner 5 and the second recliner 6 can respectively change the state of the seat configuration of the seat cushion 1 and the seat back 2 into: a first state in which the occupant can sit in a first orientation (forward); a second state in which the occupant can sit in a second orientation (backward) opposite to the first orientation; a third state in which the occupant can sit 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 located on the same plane and can be used as a bed having a wide horizontal plane SH.

[0133] In this way, the seat 91 as a vehicle seat can be arranged in various ways including forming a bed in the fourth aspect.

[0134] Similar to the seat 91, the seat 92 can also be changed in state between the first state to the fourth state independently of the seat 91. Therefore, the bench seat ST can form one or both of the seat 91 and the seat 92 into a bed.

[0135] The present invention is not limited to the above-described embodiments and procedures, and various modifications can be made without departing from the gist of the present invention.

[0136] The means of transportation is not limited to a car, and may be, for example, a railway vehicle, an airplane, a ship, an airship, or an unmanned aerial vehicle.

[0137] Although the seat 91 is installed in the vehicle with the axes CL1 and CL2 extending in the left-right direction, the present invention is not limited thereto. The seat 91 may be installed in the vehicle with the axes CL1 and CL2 extending in the front-rear direction or in the inclined direction.

[0138] The seat 91 is not limited to installing the first recliner 5 and the second recliner 6 on the same side in the width direction (the left side mentioned above). It may also be as follows: the seat 91 is a single body that is not combined with the seat 92, one of the first recliner 5 and the second recliner 6 is installed on one side in the width direction, and the other of the first recliner 5 and the second recliner 6 is installed on the other side in the width direction.

[0139] The first surface 12a of the seat cushion 1 and the first surface 22a of the seat back 2 may not be completely flat. For example, the vicinity of any one of the seat cushion bracket 32, the seat back bracket 33, the seat cushion side bracket 34, and the seat back side bracket 35 may be raised.

[0140] As described in detail above, the seat 91 as one form of the vehicle seat of the present invention comprises: a seat cushion 1; a seat back 2; a first recliner 5, which is connected to one end side of the longitudinal direction of the seat cushion 1, so that the seat cushion 1 can be tilted around an axis CL1 extending in the width direction and serving as a first axis; and a second recliner 6, which is connected to one end side of the longitudinal direction of the seat back 2, so that the seat back 2 can be tilted around an axis CL2 extending in the width direction and serving as a second axis, and the axis CL2 is spaced parallel to the axis CL1 serving as the first axis.
