Description

  The present invention relates to a mechanism for releasing a slide lock state of a vehicle seat.

For example, in a vehicle that gets on the rear seat from a door opening provided next to the front seat such as a passenger seat, the front seat is used when the passenger gets on the rear seat or gets off the rear seat. It is required that a large space for getting on and off or getting off can be secured by sliding forward, and that a seated person in the front seat can adjust the position in the front-rear direction. Therefore, the front seat includes a slide mechanism that slidably supports the seat body, a slide lock mechanism that locks the seat body at a predetermined slide position, and a slide lock release mechanism that releases the slide lock. An unlocking mechanism can be operated at the front and rear of the front seat.
A slide lock release mechanism that can be operated at the front and rear portions of the seat is disclosed in Japanese Patent Laid-Open No. 2003-31325. In this slide lock release mechanism, the front end is disposed below the front part of the seat cushion, the rear end is supported by the slide mechanism so as to be tiltable up and down, and is connected to the slide lock mechanism, so that the seat occupant holds the front end. The slide lock release handle that can be operated directly, and the front end is connected to this slide lock release handle and the rear end is located below the rear part of the seat cushion, and the rear end is gripped and pulled from the rear of the seat And an operation belt capable of remotely operating the slide lock release handle.
JP 2003-31325 A

When operating the slide lock release mechanism from the rear of the seat, the operator's body is often unstable, so that the operating force is required to be as small as possible. However, in the slide lock release mechanism described in the above publication, the force for pulling the operation belt is the force for operating the slide lock release lever as it is, and it cannot be said that the operation force is sufficiently reduced.
The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a slide lock release mechanism that can reduce the operation force when releasing the slide lock from the rear of the seat.

For this reason, the present invention is a slide lock releasing mechanism having a configuration described in each claim.
According to the slide lock release mechanism of the first aspect, when the other end of the operation member is pulled backward, the slide lock release handle is tilted to the upper slide lock release side and the slide lock state of the seat body is released. . Since the intermediate part of the operating member is hung to receive the slide lock release handle from the lower side, when the end part is pulled backward, the intermediate part slides against the slide lock release handle. As a result, the slide lock release handle is tilted upward. For this reason, the operation of the slide lock release handle performed by the pulling operation of the operation member is reduced in comparison with the case where the operation member is directly coupled to the slide lock release handle by the principle of the moving pulley.

  According to the slide lock release mechanism of the second aspect, when the other end of the operation member is pulled backward, the tilt member tilts in the lock release direction. When the tilting member tilts in the locking direction, the slide unlocking handle disposed on the tilting member tilts in the upward unlocking direction, so that the seat body is slidable. With respect to the positional relationship between the connecting portion of the operating member and the contact portion of the slide lock release handle with respect to the tilting center of the tilting member, the former is set to a greater distance than the latter. For this reason, the operation of the slide lock release handle performed by the pulling operation of the operation member is reduced as compared with the case where the operation member is directly coupled to the slide lock release handle due to the lever principle.

Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a vehicle seat 1 provided with a slide lock releasing mechanism 50 according to an embodiment described below. In this embodiment, the case where this vehicle seat 1 is set as a passenger seat of vehicle AM is illustrated. Therefore, in the following description, the vehicle seat 1 is also referred to as a front seat 1. A rear seat 5 is disposed behind the front seat 1.
The vehicle AM includes a door opening D having a large opening on the left side (passenger seat side). The door opening D is opened and closed by a slide door S. The door opening D functions as a common entrance for both passengers seated on the front seat 1 (front seat seated person) and passengers seated on the rear seat 5 (back seat seated person P).
The front seat 1 includes a seat body 10 having a seat cushion 12 and a seat back 13 and a seat support device 20 that supports the seat body 10 on the vehicle floor FL. The seat support device 20 incorporates a slide lock release mechanism 50 according to this embodiment. Since the seat body 10 does not require any change as compared with the conventional configuration, detailed description thereof is omitted.
The seat support device 20 has a function of moving the seat body 10 in the vehicle front-rear direction (left-right direction in FIG. 1) and a function of rotating in the horizontal direction. A schematic configuration of the seat support device 20 is shown in FIG. The seat support device 20 includes a first slide mechanism 21, a rotation mechanism 25, and a second slide mechanism 30. The first slide mechanism 21 and the rotation mechanism 25 are the same as those conventionally known, and need not be changed in this embodiment, but will be briefly described below.

The first slide mechanism 21 includes a slide rail 22 installed along the front-rear direction on the vehicle floor FL, a slide base 23 supported so as to be slidable in the front-rear direction of the vehicle via the slide rail 22, and a drive (not shown). Equipment. The drive device includes an electric motor as a drive source and a screw shaft mechanism that operates by this, and a conventionally known configuration is used.
The rotation mechanism 25 includes an inner ring 26 attached to the upper surface of the slide base 23, and an outer ring 27 that is rotatably and concentrically assembled with the inner ring 26 on the outer peripheral side of the inner ring 26. The outer ring 27 is attached to the lower surface of the rotation base 28. A meshing gear portion 27 a is formed on the outer peripheral surface of the outer ring 27. A driving gear that is rotated by an electric motor (not shown) is meshed with the meshing gear portion 27a. Accordingly, like the first slide mechanism 21, the rotating mechanism 25 operates using an electric motor as a drive source.
When the first slide mechanism 21 and the rotation mechanism 25 driven by the electric motors are operated in conjunction with each other, the seat body 10 moves in the vehicle front-rear direction, and the leg of the front seat occupant becomes the door opening. While avoiding interference with the edge of D (mainly the front pillar or the like), it is horizontally rotated between a position facing the front of the vehicle and a position facing the door opening D. As a result, the front seat occupant can easily get on and off the vehicle.

Next, as shown in FIG. 3, a pair of left and right second slide mechanisms 30, 30 are attached to the upper surface of the rotation base 28. Both the second slide mechanisms 30 and 30 are arranged symmetrically with each other along the left and right side portions of the rotation base 28. The sheet main body 10 is supported on the rotation base 28 via both the second slide mechanisms 30 and 30. The left and right second slide mechanisms 30 and 30 have a function of adjusting the position of the seat body 10 in the vehicle front-rear direction (so-called seat position) according to the physique of the seated person, etc. The first slide mechanism 21 is different from the first slide mechanism 21 in that it functions in a state where it is positioned in the direction. As the second slide mechanisms 30 and 30, conventionally known ones are used, and no particular change is required in the present embodiment.
The second slide mechanism 30 includes an outer rail 31 fixed on the rotation base 28, and an inner rail 32 assembled to the outer rail 31 so as to be slidable in the longitudinal direction. Between the front parts of the left and right inner rails 32, 32, a front seat bracket 33 is attached in a straddling state. Further, rear seat brackets 34 and 35 are attached to the rear portions of the left and right inner rails 32 and 32, respectively. The seat body 10 is supported on the left and right inner rails 32 and 32 via the front seat bracket 33 and the left and right rear seat brackets 34 and 35.
The sliding movement of the inner rail 32 with respect to the outer rail 31 is restricted by the slide lock mechanism 40. The slide lock mechanism 40 is provided for each of the left and right second slide mechanisms 30, 30. Both the slide lock mechanisms 40, 40 restrict the seat body 10 from moving in the front-rear direction relative to the rotation base 28 and thus the vehicle floor FL, thereby locking the seat position of the front seat 1.

As shown in FIG. 3, the slide lock mechanism 40 includes a lock base 41 attached to the upper surface of the inner rail 32, and a lock arm 43 supported so as to be tiltable up and down via a support shaft 42 with respect to the lock base 41. ing. An action portion 43 a is provided at the rear portion of the lock arm 43. This action part 43 a enters the inside of the inner rail 32. This state is shown in FIG. The action part 43a enters the inside through an opening 32a provided on the upper surface of the inner rail 32.
An engagement member 44 is attached to the inner side of the inner rail 32. In FIG. 4, the left end portion of the engaging member 44 is fixed to the upper lower surface of the inner rail 32, and the engaging member 44 is disposed along the lower portion of the action portion 43a. As shown in the figure, this engaging member 44 is formed by bending an elastic strip steel material up and down, and acts by tilting the lock arm 43 toward the unlock side as indicated by the white arrow in the figure. When the portion 43a is displaced downward, the engaging member 44 is pushed by the action portion 43a and displaced to the lower unlock position indicated by a two-dot chain line in the figure. Therefore, the downward displacement of the action portion 43 a and the tilting of the lock arm 43 toward the unlock side are performed against the elastic force of the engagement member 44.
On the other hand, when the operation force in the unlocking direction with respect to the lock arm 43 is released, the action portion 43a of the lock arm 43 is pushed back upward by the elastic force of the engagement member 44, whereby the engagement member 44 is It is returned to the upper lock position indicated by the solid line.
A plurality of engaging claws 44 a to 44 a are formed on the rear side (right end side in FIG. 4) of the engaging member 44. The engaging claws 44a to 44a protrude from the side of the inner rail 32 to the side. As described above, when the action portion 43a of the lock arm 43 is displaced up and down and the engagement member 44 moves between the lock position and the unlock position, the engagement claws 44a to 44a are also integrally displaced up and down.

On the other hand, a large number of lock claws 31a to 31a are formed on the outer rail 31 over almost the entire length thereof. In a state where the engagement member 44 is positioned at the upper lock position, the engagement claws 44a to 44a mesh with the lock claws 31a to 31a of the outer rail 31, thereby locking the movement of the inner rail 32 with respect to the outer rail 31, As a result, the movement of the seat body 10 in the vehicle longitudinal direction relative to the rotation base 28 is locked.
On the other hand, in a state where the engagement member 44 is located at the unlock position, the engagement claws 44a to 44a are disengaged from the lock claws 31a to 31a of the outer rail 31. The rail 32 becomes movable, and therefore, the movement of the seat body 10 with respect to the rotation base 28 mainly in the vehicle front-rear direction is permitted. As described above, the seat position can be adjusted in this state.
The tilting operation of the lock arm 43 toward the unlock side is performed by the slide lock release mechanism 50. The slide lock release mechanism 50 includes a slide lock release handle 45 that is operated by a front seat occupant. The slide lock release handle 45 has a generally U-shaped bent shape as shown in the figure, and the gripping portion 45a at the center thereof is located below the front portion of the seat body 10 (near the front seat occupant's feet), The rear end portions of the support portions 45b and 45b extending backward in parallel with each other from the both end portions are coupled to the slide lock mechanism 40, respectively. The rear end portions of both the support portions 45b and 45b are connected to the rear portion of the lock arm 43 so as to be vertically rotatable via a support shaft 43b. A hook 45c is provided on the rear side (front side in FIG. 3) of the grip 45a of the slide lock release handle 45. The hook portion 45c is provided between the support portions 45b and 45b so as to be parallel to the grip portion 45a.

An engaging portion 43 c is provided at the front portion of the lock arm 43. The engaging portion 43 c protrudes above the support portion 45 b of the slide lock release handle 45. For this reason, when the grip 45a of the slide lock release handle 45 is gripped and lifted upward, both the support portions 45b and 45b of the slide lock release handle 45 rotate upward about the support shaft 43b. As a result, the engaging portions 43c and 43c are pushed up by the two support portions 45b and 45b of the slide lock release handle 45 and displaced upward, and the both lock arms 43 and 43 are tilted to the unlock side about the support shaft 42, respectively. . As described above, since the tilting operation of the lock arms 43, 43 toward the unlock side is performed against the elastic force of the engaging member 44, the slide lock release handle 45 is moved upward (to the slide lock release side). The lifting operation is performed against the elastic force of the left and right engaging members 44, 44.
By tilting the slide lock release handle 45 in this manner, the lock arm 43 is tilted to the unlock side in the left and right slide lock mechanisms 40, 40, whereby the engagement member 44 is pushed to the unlock side. Thus, the engagement state of the engagement claws 44a to 44a of the engagement member 44 with respect to the lock claws 31a to 31a of the outer rail 31 is released, so that the movement of the inner rail 32 relative to the outer rail 31 is allowed.
When the lifting operation of the slide lock release handle 45 to the slide lock release side is stopped, the slide lock release handle 45 is returned downward by its own weight, so that the engaging portions 43c and 43c can be displaced downward. As a result, the left and right lock arms 43, 43 are returned to the slide lock side by the elastic force of the engaging members 44, 44. When the engaging members 44 and 44 are returned to the slide lock side shown by the solid line in FIG. 4, the engaging claws 44 a to 44 a are engaged with the lock claws 31 a to 31 a of the outer rail 31, thereby the inner rail with respect to the outer rail 31. The movement of 32 is restricted and the seat position of the seat body 10 is locked.

As shown in FIGS. 3 and 5, a rotation lock release lever 66 for releasing the rotation lock state of the rotation base 28 and the seat body 10 is provided on the upper surface of the front seat bracket 33. The rotation lock release lever 66 is supported by a bracket 61 attached to the upper surface of the front seat bracket 33 via a support shaft 62 so as to be rotatable in the horizontal direction. In the present embodiment, a conventionally known configuration is used as a rotation lock mechanism including the rotation lock release lever 66. Accordingly, although illustration and detailed description thereof are omitted, the rotation base 28 is provided with an engagement member that engages with and disengages from the slide base 23, and this engagement member engages with the slide base 23. In this state, the rotation of the rotation base 28 is restricted, and the rotation of the rotation base 28 is allowed when the engaging member is detached from the slide base 23. When the rotation lock release lever 66 is rotated in the horizontal direction, the engagement member is detached from the slide base 23 via a wire (not shown), and the rotation operation by the rotation mechanism 25 of the rotation base 28 and the seat body 10 is allowed. It becomes. When the operation of the rotation lock release lever 66 is stopped, the engagement member is returned to the position where it engages with the slide base 23 by the spring biasing force, and the rotation operation of the rotation base 28 and thus the seat body 10 is locked. .
The slide lock release mechanism 50 includes a mechanism described below for operation by a front seat occupant. Details of this mechanism are shown in FIGS. 3, 5 and 6. FIG.
A holding base 63 is fixed to the rotation lock release lever 66 bracket 61. The holding base 63 is provided with a hook pin 64. The hook pin 64 is provided so as to protrude upward from the upper surface of the holding base 63. One end side 51 a of an operation member (webbing) 51 is fixed to the holding base 63 via the hook pin 64. In this embodiment, a belt made of the same material as the seat belt webbing is used for the operation member 51.
A fixed plate 52 is attached to one end side 51 a of the operation member 51. The fixing plate 52 is provided with a fixing hole 52 a that is long in the longitudinal direction of the operation member 51. The hook pin 64 is inserted into the fixing hole 52 a and the fixing nut 65 is tightened at the tip of the hook pin 64, so that the fixing plate 52 and the one end side 51 a of the operation member 51 are fixed to the holding base 63. .

As shown in FIG. 3, two hook portions 56 and 57 are provided on the lower surface side of the front seat bracket 33 via the bracket 55. The both hooks 56 and 57 are provided in parallel to each other at a constant interval in the front-rear direction (left-right direction in FIG. 5) of the rotary base 28. Both hooks 56 and 57 are provided in parallel with the hooks 45c provided on the slide lock release handle 45, respectively. The hook portion 45c located on the most front side (left side in FIG. 3) is displaced up and down by the vertical movement operation of the slide lock release handle 45, but the rear hook portions 56 and 57 are fixed to the front seat bracket 33. Does not move up and down. Hereinafter, the foremost hook portion 45c is referred to as a moving hook portion 45c, the fixed front hook portion 56 is referred to as a front fixed hook portion 56, and the fixed rear hook portion 57 is referred to as a rear fixed hook portion 57. .
The operating member 51 is slidably hooked on the three hooks 45c, 56, and 57 along a path constituting a mechanism M (hereinafter referred to as a moving pulley mechanism) M that uses the principle of a moving pulley. That is, as shown in FIG. 5, the operation member 51 having one end 51a fixed to the front seat bracket 33 via the fixing plate 52 passes from the front side of the frontmost moving hook 45c to the front fixed hook 56. Is then routed from the front side of the rear fixed hook portion 57 to the rear side through the lower side. In a state where the operation member 51 is not operated, the intermediate portion of the operation member 51 is hung around the moving hook 45c while being bent downward in a U shape. For this reason, when the operation member 51 is pulled backward, the intermediate portion of the operation member 51 moves upward while sliding with respect to the moving hook 45c. Then, the moving hook portion 45c is pushed up by the operation member 51 and displaced upward, whereby the slide lock release handle 45 is displaced to the unlock side. When the pulling operation to the rear side of the operation member 51 is released, the slide lock release handle 45 is returned to the lower lock side by its own weight.
Since the movable pulley mechanism M is configured such that the operation member 51 is slidably hooked on the moving hook portion 45c that is displaced up and down in this way, the moving hook portion 45c of the moving hook portion 45c is configured with respect to the pulling operation amount of the operation member 51. Although the movement amount and the operation amount of the slide lock release handle 45 to the unlocking side are approximately halved, the operation force required for the unlocking operation is approximately half that of the conventional configuration. Thus, the slide lock release handle 51 can be operated to the unlock side with a smaller operating force.

Next, as shown in FIG. 6, the operation member 51 is routed rearward and reaches the rear portion of the sheet support device 20. The operation member 51 is routed from the front part to the rear part substantially along the upper surface of the rotation base 28.
Three hooks 58, 59, 60 are also provided on the seat bracket 34 provided at the rear part of the left side of the rotation base 28 in the rear part of the seat support device 20. The rear portion 51 b of the operation member 51 is coupled to the rear hook portion 60 via the front hook portion 58 and the central hook portion 59. As shown in the figure, the rear portion 51b of the operation member 51 is provided with two loop portions 51c and 51d. The rear portion 51b is coupled to the hook portion 60 in a state where the hook portion 60 is inserted into the front loop portion 51c. Has been. Accordingly, the operation member 51 can be pulled within a range in which the hook portion 60 can be relatively displaced in the front loop portion 51c, and accordingly, the hook portions 58 to 60 of the rear portion 51b of the operation member 51. As a result, the rear loop portion 51d is always kept protruding from the rear portion of the seat support device 20, as shown in FIG. The rear loop portion 51d mainly functions as a finger hooking portion for hooking a finger when the rear seat occupant P pulls the operation member 51. Therefore, the loop portion 51d (finger hooking portion) is located at a position where the rear seat occupant P can see and easily operate, and the operability of the operation member 51 is ensured. In the present embodiment, the loop portion 51d corresponds to the other end of the operation member described in the claims.
As described above, the movable pulley mechanism M including the slide lock release handle 45, the operation member 51, and the hooks 45c and 56 to 60 constitutes the slide lock release mechanism 50 of the present embodiment.

According to the slide lock release mechanism 50 configured as described above, since the operation member 51 operated mainly by the rear seat occupant P is connected to the slide lock release handle 45 via the movable pulley mechanism M, the operation member 51 is operated. The remote operation to the unlock side of the slide lock release handle 45 by the above operation can be performed with a smaller operation force than when the operation member 51 is directly connected to the slide lock release handle 45.
In addition, since the operation portion (loop portion 51d) of the operation member 51 is provided on the seat support device 20 side and is not provided on the seat body 10 side, the configuration of the slide lock release mechanism 50 and the function thereof are provided. All of them are incorporated into the sheet support device 20 and unitized. Therefore, the versatility can be enhanced by forming the slide lock release mechanism 50 together with the seat support device 20 as a common unit for the seat main body 10 of various forms prepared according to the vehicle type.

Various modifications can be made to the embodiment described above. For example, the configuration (first embodiment) using the movable pulley mechanism M in order to reduce the operating force of the remote operation of the slide lock release handle 45 by the operating member 51 is illustrated, but instead of this, for example, as shown in FIG. The same effect as that of the first embodiment can also be obtained by the slide lock releasing mechanism 70 (second embodiment) using the tilting member 71. With respect to members and configurations that do not need to be changed as compared with the first embodiment, the description is omitted by using the same reference numerals.
The slide lock release mechanism 70 according to the second embodiment includes a lever bracket 72 provided on the front seat bracket 33. The tilting member 71 is supported by the lever bracket 72 via a support shaft 73 so as to be rotatable up and down. As shown in the figure, the tilting member 71 extends forward through the lower side of the moving hook 45c of the slide lock release handle 45. The tip of the actuating wire 75 is connected to the turning tip of the tilting member 71 that has passed through the moving hook 45c. The operating wire 75 is inserted through the tube 76. The distal end portion of the tube 76 is fixed to a bracket 76 a attached to the front seat bracket 33. When the operating wire 75 is pulled upward, the tilting member 71 rotates upward (clockwise in FIG. 7).
When the tilting member 71 is pivoted upward, the tilting member 71 is pushed up to displace the moving hook 45c of the slide lock release handle 45 so that the slide lock release handle 45 is indicated by a two-dot chain line in FIG. It is displaced to the upper unlocking position shown in the figure, whereby the lock state of the left and right second slide mechanisms 30 and 30 is released, and the seat body 10 can be moved in the vehicle front-rear direction.
When the upward pulling operation of the actuating wire 75 is released, the tilting member 71 is returned downward by the weight of the slide lock release handle 45, and thus the slide lock release handle 45 is returned to the lower lock position and the seat body. 10 is fixed to the adjusted seat position.
The tube 76 inserted through the working wire 75 is routed rearward along the upper surface of the rotary base 28. The rear portion of the tube 76 is fixed to a bracket 76b attached to the upper rear portion of the rotary base 28. The rear end portion of the working wire 75 is pulled out from the rear portion of the tube 76, and the rear end portion is connected to the operation belt 77. As in the first embodiment, the rear portion of the operation belt 77 is passed through two hook portions 58 and 59, and the hook portion 60 is inserted into a loop portion 77a provided at the rear portion thereof.
The operation belt 77 and the operation wire 75 correspond to an example of an operation member described in the claims. Further, the loop portion 77a at the rear end portion of the operation belt 77 corresponds to the other end described in the claims.

According to the slide lock release mechanism 70 according to the second embodiment configured as described above, when the rear seat occupant P pulls the fingertip on the loop portion 77a of the operation belt 77, the actuation wire 75 is pulled backward. Accordingly, the tilting member 71 rotates upward about the support shaft 73, whereby the slide lock release handle 45 is tilted to the upper unlock position, and the seat position of the seat body 10 can be adjusted. When the fingertip is removed from the loop portion 77a of the operation belt 77 and the pulling operation of the operating wire 75 is stopped, the tilting member 71 is returned downward by the weight of the slide lock release handle 45, and therefore the slide lock release handle 45 is slid downward. Returning to the locked position, the seat body 10 is locked at the position after the seat position adjustment.
Here, the operation force f for pulling the loop portion 77a of the operation belt 77 to move the slide lock release handle 45 to the unlock position is:
f = (R1 / R2) × (R4 / R3) × F.
In addition,
F: Necessary operating force for gripping the grip portion 45a of the slide lock release handle 45 and tilting it directly to the unlock position R1: Arc movement around the support shaft 43b of the grip portion 45a of the slide lock release handle 45 Radius R2: Arc movement radius R3 centered on the support shaft 43b of the hooking portion 45c: Arc movement radius R4 of the tilting member 71 centered on the support shaft 73 of the connecting portion 71a of the operating wire 75 R4: Tilt of the tilting member 71 Thus, the average value of the arc moving radii around the support shaft 73 of the hooking portion 45c is connected to the slide lock release handle 45 through the tilting member mechanism L in this way, and the tilting center of the tilting member 71 is More than the distance R4 between the support shaft 73 and the contact portion between the moving hook portion 45c of the tilting member 71, the support shaft 73 and the operating wire 75 of the tilting member 71 are Since the distance R3 to the connecting portion 71a is longer, the pulling operation force of the operation belt 77 compared to the operation force (= F × (R1 / R2)) required to move the moving hook 45c directly upward. Therefore, the rear seat occupant P can easily release the slide lock state of the front seat by remotely operating the slide lock release handle 45 with a small operation force f.
Also in the second embodiment, the operation portion (loop portion 77a) of the operation belt 77 is provided on the seat support device 20 side, and is not a configuration provided on the seat body 10 side. All of the configurations and functions of 70 are incorporated into the sheet support operation 20 and unitized. From this, like the said 1st Embodiment, the sheet | seat support apparatus 20 can be made into a common unit with respect to the sheet | seat main body of various forms, and, thereby, the versatility of the said sheet support apparatus 20 can be improved.
Furthermore, the appearance of the sheet body 10 can be improved for the same reason as in the first embodiment.

In the first and second embodiments described above, the vehicle AM in the form in which the door opening D having a large opening is provided on the side of the vehicle AM and the door opening D is opened and closed by the slide door S is illustrated. The present invention can be similarly applied to a vehicle provided with a so-called hinge door of a horizontal rotation type.
Further, in the second embodiment, the configuration in which the operation belt 77 is connected to the tilting member 71 via the operation wire 75 is illustrated, but a configuration in which the operation belt 77 is directly connected to the operation member may be employed. Conversely, a loop portion or a gripping portion to be gripped by the rear seat occupant P is provided at the rear end portion of the operating wire 75, and the gripping portion is positioned at the rear portion of the front seat so that the operation belt 77 is omitted. Good. In this case, the operating wire corresponds to the operating member described in the claims. Therefore, the operation member described in the claims includes not only a belt having a certain width but also a wire, a cable, or a rod.
Furthermore, in 2nd Embodiment, although the actuating wire 75 was connected to the same side with respect to the tilting center (supporting shaft 73) of the tilting member 71, and the moving hook part 45c contacted, the tilting center was illustrated. In contrast, the operating wire 75 may be connected to the opposite side to each other, and the moving hook portion 45c may be brought into contact. In this case, when the loop portion 77a of the operation belt 77 is pulled, the connecting portion of the operating wire with respect to the tilting member is displaced downward, so that the moving hook portion is displaced upward, and the slide lock release handle is locked upward. It can be configured to be operated in the release direction.
Moreover, although the vehicle AM of the form in which the seated person P of the front seat and the seated person P of the rear seat get on and off through the common door opening part D was illustrated, the form (for example, 4-door sedan) which gets on and off through each separate door opening part It can also be applied to a type of passenger car).
Furthermore, a vehicle suitable for a so-called welfare vehicle that can easily get on and off by providing the seat support device 20 that is rotated by the rotation mechanism 25 while the seat body 10 is slid in the vehicle longitudinal direction by the first slide mechanism 21. Although the case where it applied to the vehicle seat 1 was illustrated, the seat position can be adjusted by the second slide mechanism, it can also be applied to a normal vehicle seat that is fixed in the front direction of the vehicle and does not rotate.
Moreover, although the example applied to the front seat part of the vehicle provided with the front seat part and the rear seat part as a vehicle seat was shown, for example, the operation member can be operated from the rear such as a seat in which the rear is a luggage compartment As long as it is a sheet, it can be applied to any sheet.
