Description

  The present invention relates to a vehicle seat capable of slidingly adjusting a seating position in a vehicle interior.

In recent years, in a vehicle such as a minivan, it is desired to diversify the seat arrangement of the rear seat, and it is desired that the amount of sliding movement of the seat in the longitudinal direction of the vehicle body is further increased.
However, when trying to increase the front / rear slide amount of the rear seat, the installation position of the seat in the vehicle width direction is avoided in order to avoid interference between the rear wheel house that bulges from the vehicle body side to the vehicle interior and the seat. Will be limited.

For this reason, as a vehicle seat that can cope with this problem, at least a part of the slide rail is inclined outward in the vehicle width direction from the rear side of the vehicle body toward the front side, and the seat is inclined to the bulging portion of the rear wheel house. A device that can slide forward has been devised (for example, see Patent Documents 1 and 2).
In this vehicle seat, the rearmost end moving position of the seat is set on the inner side in the vehicle width direction of the bulging portion of the rear wheel house, while the frontmost moving position of the seat is set at the front position of the bulging portion of the rear wheel house. When the seat is moved to the foremost end movement position, a large effective space is secured in the inner region of the seat in the vehicle width direction.

An armrest 12 is provided for the passenger m to place his / her arm. The upright wall 11 is formed in a substantially box shape that is long in the front-rear direction and the up-down direction, and accommodates a frame member (not shown), a lever component for reclining operation, and the like.

  A rear wheel house 13 that covers the outer side of the rear wheel bulges inward in the vehicle width direction on the side of the vehicle 1 (the area between the quarter pillar 6 and the rear pillar 7). The rear wheel house 13 is integrally provided on the vehicle body panel on the side of the vehicle. A retractor 15 (see FIGS. 2 and 4) of the seat belt device 14 for the second row of seats 2B is fixedly installed at a position above the rear wheel house 13 in the vehicle body panel via a bracket (not shown). Has been. A rear side lining 16, which is a resin interior member, is attached to the vehicle interior side region between the quarter pillar 6 and the rear pillar 7 by screws, locking clips, or the like.

The seat belt device 14 of the second row of seats 2B is a three-point seat belt device, and the webbing 17 pulled out from the retractor 15 is pulled out into the vehicle interior through the drawer port 18 of the rear side lining 16, and the leading end thereof is a quarter pillar. 6 is fixed on the vehicle body floor 20 via an outer anchor 19 in the vicinity of the lower end. A tongue plate 21 is inserted in a region located between the drawer opening 18 and the outer anchor 19 on the webbing 17, and the tongue plate 21 is a buckle fixed to the vehicle body floor 20 on the inner side in the vehicle width direction of the seat 2B. 22 is removable.
The webbing 17 is wound around the retractor 15 at the base end in the initial state, and the occupant m grips and pulls out the tongue plate 21 portion by hand, and fixes the tongue plate 21 to the buckle 22. The chest and waist are restrained against the seat 2B.

  By the way, the seats 2B in the second row are slidable in the longitudinal direction of the vehicle body through a pair of seat rails 23 installed on the vehicle body floor 20, more precisely in the diagonally longitudinal direction on the left and right sides of the vehicle body. Yes. As shown in FIGS. 3 and 5, the seat rail 23 is installed on the vehicle body floor 20 so that the front side is inclined outward in the vehicle width direction. The seat 2B that slides on the seat rail 23 is positioned on the inner side in the vehicle width direction from the bulging portion 13a of the rear wheel house 13 at the rearmost end moving position shown in FIGS. In the foremost end movement position shown, it is located on the front side of the bulging portion 13a of the rear wheel house 13 on the outer side in the vehicle width direction than the rearmost end movement position. Therefore, the seat 2B in the second row of this embodiment can secure a sufficiently large separation distance between the left and right adjacent seats 2B in the state in the vicinity of the foremost end movement position, and the rear wheel house. It can be slid to the rearmost end movement position without causing interference with the 13 portions.

In addition, when the seat 2B in the second row of this embodiment is not in use, the seat back 9 is folded in half on the seat cushion 8, and the entire seat 2B is flipped forward in the state at the foremost end moving position. A so-called tumble operation is possible.
FIG. 7 is a diagram showing a main configuration for realizing the tumble operation of the second row of sheets 2B, and FIG. 8 shows the tumble operation of the sheet 2B sequentially in time series from (A) to (E). FIG.

  As shown in FIG. 7, in the seat 2 </ b> B, a plate-like slide base 24 is slidably supported on a seat rail 23 (lower rail) laid on the vehicle body floor 20, and a rotating hinge 25 is mounted on a front end portion of the slide base 24. The front end portion of the seat cushion 8 is connected to be able to turn back and forth. A seat back 9 is rotatably connected to the rear end portion of the seat cushion 8 via a reclining mechanism 26. Further, a tumble striker 27 made of a substantially U-shaped bar-like member protrudes from the rear end portion of the slide base 24, and a lock mechanism 28 provided at the lower end of the rear portion of the seat back 9 engages with the tumble striker 27. It is like that.

The reclining mechanism 26 is released by operating either a reclining release lever 33 provided at the side of the seat cushion 8 or a reclining release strap 34 provided at the rear end of the standing wall 11 below the armrest 12. It is like that.
In addition, when the reclining mechanism 26 is released, the seat back 9 rotates about the rotation shaft 26a of the reclining mechanism 26 and transitions to a two-stage forward tilted state. That is, the seat back 9 is in a half-tilt state in which it is tilted forward about half before the tumble operation is completed, and then in a full-tilt state in which the seat back 9 is tilted until it overlaps with the seat cushion 8. A semi-falling stopper 31 is provided at the rear end portion of the seat cushion 8, and when the reclining mechanism 26 is released, the stopper pin 32 on the seat back 9 side comes into contact with the half-falling stopper 31. The seat back 9 is maintained in a half-turned state. A slide lock mechanism 35 that locks the slide position of the slide base 24 is provided between the slide base 24 and the seat rail 23. When the seat 2B is not operated at all, the slide lock mechanism 35 maintains the slide base 24 in the locked state.

  As described above, the slide lock mechanism 35 is unlocked in response to the operation of the seat back 9 when the seat back 9 is in a half-tilt state by the release operation of the reclining mechanism 26. When the seat cushion 8 (slide base 24) is slid to the foremost end movement position after the slide lock mechanism 35 is released, the half-falling stopper 31 is then unlocked at the rear end of the seat cushion 8. When 36 is pulled, it is displaced away from the stopper pin 32. As a result, the seatback 9 is released from the rotation restriction by the half-falling stopper 31 and transitions to the full-falling state.

  The locking mechanism 28 that locks the rotation of the front side of the seat cushion 8 is engaged with the tumble striker 27 on the slide base 24 in the normal state, but the seat cushion 8 (slide base 24) is the most. When the seat back 9 moves to the front end movement position and transitions to the all-falling state, the engagement with the tumble striker 27 is released in response to the operation.

Here, a specific tumble operation of the seat 2B will be described with reference to FIGS.
First, when the seat 2B is in the normal posture (the posture in which the seat back 9 stands up rearward), either the reclining release lever 33 or the reclining release strap 34 is operated as shown in FIG. Then, the seat back 9 is tilted forward about the rotating shaft 26a of the reclining mechanism 26 and is in a semi-falling state. Thus, when the seat back 9 is in a half-turned state, the lock of the slide lock mechanism 35 is released.

Next, when the occupant m pushes the seat 2B forward from this state, the seat 2B slides and moves obliquely forward along the seat rail 23 as shown in FIG. 8B. When the seat 2B moves to the foremost end movement position in this manner, the seat back 9 can be shifted to the fully-falling state due to the lock release strap 36 being pulled.
From this state, as shown in FIG. 8C, when the unlocking strap 36 is pulled, the seat back 9 is fully tilted about the rotating shaft 26a of the reclining mechanism 26, and the locking mechanism 28 and the tumble striker 27 are The engagement is released.

  When the engagement of the lock mechanism 28 and the tumble striker 27 is released in this way, the entire seat 2B is rotated as shown in FIG. 8D by the force of a biasing spring (not shown) built in the rotation hinge 25. Slowly rotates (tumbles) around the hinge 25. Thereafter, the seat 2B is locked and fixed to the skeleton member of the vehicle body by the locking tool 37, as shown in FIG.

  In addition, the seat 2C in the third row in the passenger compartment shown in FIG. 1 is pivoted to the seat cushion 108 that supports the buttocks of the occupant m and the rear end portion of the seat cushion 108, like the seat 2B in the second row. A seat back 109 that is connected so as to support the waist and chest (back) of the occupant, and a headrest 110 that is attached to the upper portion of the seat back 109 and supports the head and neck of the occupant. . The seats 2C in the third row are stored in recesses (not shown) provided on the vehicle body floor 20 at the rear of the vehicle interior, and project from the recesses onto the vehicle body floor 20 during use. In the seat 2C, the seat back 109 is folded in half on the upper surface side of the seat cushion 108 and is stored in the recess in this state, so that the back of the seat back 109 closes the opening of the recess. Further, the lower end of the seat cushion 108 is supported on the bottom wall in the recess through a link mechanism (not shown), and the seat 2C is stored in the recess and protrudes onto the vehicle body floor 20 by the operation of the link mechanism. It can be done as appropriate.

When the seat 2C in the third row is not used as a seat as described above, the seat back 109 and the seat cushion 108 are thinner than the seat 2B in the second row because of being stored in the recess of the vehicle body floor 20. The seating surface 108a of the seat cushion 108, in particular, the rear region of the seating surface 108a is lower than the seating surface 8a of the seat 2B in the second row.
When used as a seat, the seat 2 </ b> C installed on the vehicle body floor 20 is positioned on the rear side of the rear door opening 4.

A box-shaped pedestal portion 38 that bulges inward in the vehicle width direction from a lower position of the window frame portion 29 is integrally formed with the rear side lining 16 attached to the vehicle body side portion in the vehicle interior. The pedestal portion 38 protrudes inward in the vehicle width direction at a height position substantially equal to the seat back 9 of the second row of seats 2B.

The front end portion of the webbing 17 arranged along the guide surface 39 extends from the front end position of the guide surface 39 toward the outer anchor 19 near the lower end of the quarter pillar 6. When the seat belt device 14 is not used, the webbing 17 receives the pulling force by the retractor 15 by hooking the midway portion along the guide surface 39 and hooking it on the corner portion on the front end side of the pedestal portion 38. Locked on top.

  A recess 40 that is recessed outward in the vehicle width direction is formed on the lower side of the pedestal portion 38 of the rear side lining 16, and a box-like armrest portion 41 that is long in the front and rear is formed at the lower end of the recess 40. It bulges inward in the direction. The armrest portion 41 has an upper surface formed substantially horizontally, and an arm of an occupant m seated on the seat 2C in the third row is placed on the upper surface. The armrest portion 41 extends in the longitudinal direction of the vehicle body to the vicinity of the rear edge portion of the door opening 4 substantially parallel to the upper surface of the pedestal portion 38.

  Between the front edge portion of the pedestal portion 38 of the rear side lining 16 and the front edge portion of the armrest portion 41, an assist grip 42 having a substantially U-shaped side view is integrally attached. The assist grip 42 has a grip portion 42a gripped by the occupant m extending in the vertical direction of the vehicle body, and an upper bent base portion 42b is overlapped and joined to the vehicle interior side of the front edge portion of the pedestal portion 38. In addition, the lower bent base portion 42c is overlapped and coupled to the vehicle interior side of the front edge portion of the armrest portion 41.

  As shown in FIG. 9, the guide surface 39 on the pedestal portion 38 is gently inclined forward from the upper surface side of the pedestal portion 38 toward the front end side, and is curved so that the front side smoothly continues to the front end surface. doing. The bent base portion 42b on the upper side of the assist grip 42 is formed so that the shape of the upper edge portion thereof substantially follows the shape of the front edge portion of the guide surface 39 of the pedestal portion 38 and is slightly larger than the contour of the guide surface 39. Yes. That is, the upper edge portion of the bent base portion 42 b protrudes at a predetermined height from the upper side and the front side of the guide surface 39 at the vehicle width direction inner side position of the guide surface 39. The protruding portion of the upper edge portion of the bent base portion 42 b constitutes a regulating wall 55 that regulates displacement in the vehicle width direction of the webbing 17 disposed along the guide surface 39. A regulating protrusion (not shown) that regulates the upward displacement of the webbing 17 disposed along the guide surface 39 is integrally formed on the outer surface of the regulating wall 55 in the vehicle width direction.

By the way, as shown in FIGS. 6 and 9, on the upper part of the seat back 9 of the seat 2B in the second row, when the webbing 17 is mounted, the webbing 17 pulled out from the outlet 18 toward the shoulder of the occupant m.

And an extending portion 47 extending downward. The standing portion 46 is formed in a substantially right triangle shape when viewed from the front, and stands so that one side facing the oblique side is substantially parallel to the side surface of the headrest 10. The extension portion 47 is formed at the end of the upright portion 46 on the outer side in the vehicle width direction so that the outer surface is substantially continuous with the slope 46 a of the upright portion 46. The extended portion 47 slightly protrudes outward with respect to the inclined surface 9a on the side portion of the seat back 9.

FIG. 10 is a view showing a state where a passenger m having a relatively small physique sits on the seat 2B and wears the webbing 17, and FIG. 10A shows a state where the seat 2B is in the foremost end movement position. FIG. 10B is a front view when the seat 2B is at the rearmost end movement position. 11 and 12 are views showing a state in which a relatively large occupant m is seated on the seat 2B and the webbing 17 is attached. FIG. 11A shows the seat 2B at the foremost end. FIG. 11B and FIG. 12 are a front view and a perspective view when the seat 2B is at the rearmost end movement position.
In this embodiment, since the outlet 18 of the webbing 17 in the rear side lining 16 is disposed at substantially the same height as the seat back 9 of the rear side of the slidable sheet 2B, occupant seated on the seat 2B The pull-in position of the webbing 17 on the seat back 9 changes according to the shoulder height of m, the front / rear slide position of the seat 2B, and the like.

That is, as shown in FIG. 10A, an occupant m having a relatively small physique (for example, a shoulder height lower than that of the seat back 9) is seated on the seat 2B at the foremost end movement position, and the webbing is performed in that state. When the seat 17 is mounted, the drawer opening 18 is positioned on the more back side of the seat back 9 by the oblique sliding movement of the seat 2B to the front side, and the webbing 17 is in sliding contact with the extension 47 of the webbing guide 45 so that the seat back 9 It is drawn into the front side of the seat back 9 from the inclined surface 9a.
Further, as shown in FIG. 10B, when an occupant m having a relatively small physique sits on the seat 2B at the rearmost end movement position and the webbing 17 is attached in this state, the seat 2B slides obliquely toward the rear side. Due to the movement, the drawer opening 18 is disposed at a position close to the right side portion of the seat 2B, and the webbing 17 is in sliding contact with the extension 47 of the webbing guide 45, and from the inclined surface 9a of the seat back 9 to the front side of the seat back 9. It can be withdrawn.

On the other hand, as shown in FIG. 11A, an occupant m having a relatively large physique (for example, the shoulder height is higher than that of the seat back 9) is seated on the seat 2B at the foremost end movement position, and in this state When the webbing 17 is mounted, the drawer port 18 is positioned on the more back side of the seat back 9 by the oblique sliding movement of the seat 2B to the front side, and the webbing 17 is in sliding contact with the inclined surface 46a of the standing part 46 of the webbing guide 45, The seat back 9 is pulled into the front side of the seat back 9 from a position above the inclined surface 9a.
Further, as shown in FIG. 11B, when an occupant m having a relatively large physique sits on the seat 2B at the rearmost end movement position and the webbing 17 is attached in this state, the seat 2B slides obliquely toward the rear side. Due to the movement, the drawer opening 18 is disposed at a position close to the right side portion of the seat 2B, and the webbing 17 is in sliding contact with the inclined surface 46a of the standing portion 46 of the webbing guide 45 as shown in FIG. It is drawn into the front side of the seat back 9 from a position above the inclined surface 9a.
At this time, the webbing 17 may move in the headrest 10 direction on the upper side of the seat back 9 if there is no standing portion 46 of the webbing guide 45. However, in the seat 2B, the webbing 17 moves in the headrest 10 direction. Is regulated by the standing portion 46.

The webbing 17 is always restricted to an appropriate position, and the upper body of the occupant m can be reliably restrained without causing the occupant m to feel uncomfortable.
In particular, in the seat 2B in which the relative position in the vehicle width direction with respect to the drawer port 18 changes by sliding back and forth obliquely with respect to the vehicle body as in this embodiment, the drawer port 18 is located on the right side portion of the seat back 9. Under close proximity, the pull-in position of the webbing 17 from the seat back 9 can easily follow the operation of the occupant m and the behavior of the upper body. For this reason, when an occupant with a relatively large physique wears the webbing 17, there is an increased possibility that the webbing 17 tends to be displaced toward the headrest 10 depending on the movement position of the seat 2B. In the seat 2B of this embodiment, however, Can effectively restrict the displacement of the webbing 17 toward the headrest 10 by the standing portion 46 of the webbing guide 45.

  Further, in the seat 2B of this embodiment, the webbing guide 45 is provided with the extension portion 47 extending to the outer side surface (inclined surface 9a) in the vehicle width direction of the seat back 9, so that the occupant having a small physique Even when the m wears the webbing 17, the webbing 17 is slid by the extension 47, so that the webbing 17 is pulled into the front side of the seat back 9 according to the height of the shoulder of the occupant m. It can be easily changed. Therefore, the occupant m can be reliably restrained by the webbing 17 regardless of the physique of the occupant m and the front / rear slide position of the seat 2B.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, although the case where the present invention is applied to a vehicle in which three rows of seats are arranged in the front and rear in the vehicle interior has been described here, the vehicle to be applied may be a vehicle in which two rows of seats are arranged in the front and rear.
