<< Embodiment 1 >>
(Vehicle structure)
The vehicle structure 1 according to the first embodiment includes a first seat 10 and a second seat 20 arranged along the front-rear direction of the vehicle. Both the first seat 10 and the second seat 20 are slide sheets that can slide in the front-rear direction of the vehicle. The first sheet 10 and the second sheet 20 have a slide range where the two sheets 10 and 20 come into contact with each other. The second seat 20 has a lever 22 for locking and releasing the slide of the second seat 20. One of the features of the vehicle structure 1 is that the lever 22 of the second seat 20 is mechanically operated so that the slide of the second seat 20 is unlocked when the first seat 10 contacts the two seats 10 and 20. It has a lock release unit 13 for displacing. Hereinafter, each configuration will be described in detail. In this example, a vehicle structure of a front-back two-row seat type will be described as an example. The first seat 10 is a first-row seat (front seat) located on the front side of the vehicle, and the second seat 20 is a second-row seat (rear seat) located on the rear side of the vehicle. The rear side of the vehicle of the second seat 20 is a luggage compartment.

  1 to 4, the first seat 10 and the second seat 20 indicate a first row seat and a second row seat on the right side of the vehicle. FIGS. 1 and 2 show a state where both the first sheet 10 and the second sheet 20 are arranged at positions on the front side of the sliding range. That is, the first sheet 10 and the second sheet 20 show a state where they are not in contact with each other. The first sheet 10 shown by a two-dot chain line in FIGS. 3 and 4 shows a state where it is arranged at the same position as the first sheet 10 shown in FIGS. 1 and 2. The solid line in FIG. 3 and the broken line in FIG. 4 show a state in which the first sheet 10 is slid backward from a position on the front side of the sliding range to a position where it comes into contact with the second sheet 20. The solid line in FIG. 4 indicates a state in which the first sheet 10 is slid further back from the position in contact with the second sheet 20 and the first sheet 10 and the second sheet 20 are moved to positions on the rear side of the sliding range. Is shown. The two-dot chain line in FIG. 5 indicates that the rear cover 14 of the first sheet 10 and the lever 22 of the second sheet 20 in a state where both the first sheet 10 and the second sheet 20 are arranged at positions on the front side of the sliding range. Show. The lever 22 is in a locked position. 5 shows the rear cover 14 of the first sheet 10 and the lever 22 of the second sheet 20 in a state where the first sheet 10 and the second sheet 20 are in contact with each other. This lever 22 shows a state where it is displaced from the locked position to the unlocked position by the unlocking portion 13 provided on the rear cover 14. The solid line in FIG. 6 is a cross-sectional view of the center cover portion 141 of the rear cover 14, and shows the occupant's foot 300 for convenience of explanation. 6 shows a state in which the center cover 141 is deformed due to the contact between the center cover 141 and the occupant's foot 300.

[First sheet]
The first seat 10 has a seat cushion 111 serving as a seat surface of the occupant, a seat back 112 supporting the back of the occupant, and a headrest 113 supporting the head of the occupant (FIGS. 1 to 4). The seat cushion 111 is fixed to a seat cushion frame (not shown) forming a skeleton of the seat cushion 111. The seat cushion frame is covered with a side cover 16 described later, and is not shown in FIGS. 1 to 4.

  The first seat 10 is slidably provided in the front-rear direction of the vehicle. The sliding of the first seat 10 back and forth is performed by sliding an upper rail (not shown) with respect to the lower rail 17. The lower rail 17 is fixed on the front floor panel 50 along the front and rear of the vehicle so as not to slide in the front and rear of the vehicle. The rear end of the lower rail 17 of this example is disposed near the front end of a lower rail 27 of the second seat 20 which will be described later. The upper rail is connected to the seat cushion frame (not shown). In this example, the connection between the upper rail and the seat cushion frame is performed via a rail bracket (not shown). Like the seat cushion frame, the upper rail and the rail bracket are covered with a side cover 16 described later, and are not shown in FIGS. 1 to 4.

  The first sheet 10 has a slide range that comes into contact with the second sheet 20. Having a sliding range to contact means that the first sheet 10 and the second sheet 20 contact each other as the distance between the first sheet 10 and the second sheet 20 is reduced. The first seat 10 is a manual seat (manual seat) in which the slide movement before and after the first seat 10 is manually released by unlocking the slide. The first seat 10 has a lever 12 that is operated by an occupant's hand.

  The lever 12 is provided so as to be freely displaceable within a range between a lock position for locking the slide of the first seat 10 and a lock release position for releasing the lock. In this example, the locked position is when the lever 12 is located below as shown by the solid line in FIGS. 1 and 2 and the two-dot chain line in FIGS. In the present example, the lock release position is when the lever 12 is located upward as shown by the solid line in FIG. 3, the broken line and the solid line in FIG. That is, when the lower lever 12 is displaced upward, the slide of the first sheet 10 is unlocked, and when the upper lever 12 is displaced downward, the slide of the first sheet 10 is locked. The lever 12 may be urged downward, or may not be urged downward. In this example, the position of the lever 12 is on the front side below the seat cushion 111. The lever 12 is connected to a lock mechanism (not shown) for locking the slide of the upper rail. Known configurations can be used for the connection relationship between the lever 12 and the lock mechanism and the configuration of the lock mechanism. The shape of the lever 12 is C-shaped in this example.

(Lock release section)
The lock release unit 13 displaces the lever 22 of the second sheet 20 from the locked position to the unlocked position when the first sheet 10 comes into contact with the second sheet 20 due to the sliding of the sliding range backward. The position where the lock release portion 13 is disposed is on the side of the first sheet 10 facing the second sheet 20 (lever 22). The location of the lock release portion 13 in the present example is on the first seat 10 on the rear side of the vehicle.

  The lock release unit 13 of this example is provided on a rear cover 14 described later. That is, the lock release unit 13 is configured by a part of the rear cover 14. Specifically, the lock release section 13 is configured by an inclined surface of the left cover section 142 of the rear cover 14.

  The rear cover 14 covers below the seat cushion 111 (first seat 10) from the rear side of the vehicle. The rear cover 14 is provided at a lower portion of the first seat 10 behind the vehicle. The rear cover 14 in this example has a center cover 141, a left cover 142, and a right cover 143. The center cover 141, the left cover 142, and the right cover 143 are integrally formed. The rear cover 14 has a gate shape when viewed from the rear side of the vehicle.

  As shown in FIG. 6, the center cover portion 141 covers the rear side portion 151 of the seat cushion frame from the rear side of the vehicle. The rear side 151 is arranged to extend in the vehicle width direction behind the vehicle. The shape of the rear side portion 151 is cylindrical in this example, but is not particularly limited, and may be a rectangular cylindrical shape or the like. The cross-sectional shape of the center cover 141 is L-shaped, and the center cover 141 covers the rear side 151 from above to behind. The central cover part 141 is arranged so as to leave a predetermined space between the central cover part 141 and the rear side part 151. For this reason, when the foot 300 of the occupant sitting on the second seat 20 enters below the central cover portion 141 and comes into contact with the central cover portion 141, the lower end portion of the central cover portion 141 is moved as shown by a two-dot chain line in FIG. Then, it is deformed toward the front side of the vehicle so as to approach the rear side 151. Thereby, an excessive collision between the center cover part 141 and the occupant's foot 300 can be suppressed.

  The left cover part 142 and the right cover part 143 cover, for example, the rear ends of the left and right sides (not shown) of the seat cushion frame and the rear ends of the rail brackets (not shown) from the rear side of the vehicle (FIG. 1). The left side and the right side of the seat cushion frame are arranged so as to extend in the front-rear direction of the vehicle, and each end of the rear side 151 and a front side (not shown) parallel to the rear side 151 in front of the vehicle. To each end. The left cover part 142 and the right cover part 143 are connected to the rear end of each side cover 16. Each side cover 16 covers below the seat cushion 111 (first seat 10) from the side of the vehicle.

  The rear surfaces of the left cover part 142 and the right cover part 143 have inclined surfaces that rise upward toward the front side of the vehicle (FIGS. 1 and 5). In this example, the inclined surface of the left cover part 142 constitutes the lock release part 13. The position of the inclined surface is a position where it contacts a left side portion 222 (described later) of the lever 22 at the lock position of the second seat 20. The inclination angle of the inclined surface depends on the angle and position of the front side of the left side part 222, but is preferably larger than the inclination angle of the front side of the left side part 222. Then, when the inclined surface (the unlocking portion 13) of the left cover portion 142 comes into contact with the lever 22 in the locked position, the left side portion 222 of the lever 22 on the inclined surface (the unlocking portion 13) of the left cover portion 142. Easy to slide the front part of the. Therefore, the lever 22 is easily displaced from the lock position to the lock release position by the lock release unit 13. When the left cover part 142 is viewed from the side, the inclination angle of the inclined surface refers to the smaller one of the angles formed by the direction parallel to the inclined surface and the longitudinal direction of the vehicle.

[Second sheet]
In this example, the second seat 20 has a seat cushion 211, a seat back 212, and a headrest 213 as in the first seat 10 (FIGS. 1 to 4). The seat cushion 211, like the first seat 10, is fixed to a seat cushion frame (not shown). The seat cushion frame is covered with a side cover 26 described below, and is not shown in FIGS.

  The second seat 20 is provided slidably in the front-rear direction of the vehicle by sliding the upper rail 28 (FIG. 2) with respect to the lower rail 27, similarly to the first seat 10. The lower rail 27 is fixed on the rear floor panel 60 along the front and rear of the vehicle so as not to slide in the front and rear of the vehicle. The rear floor panel 60 is formed continuously from the front floor panel 50 on the rear side of the vehicle. The rear floor panel 60 is located above the front floor panel 50 in this example. The upper rail 28 is connected to the seat cushion frame (not shown) via a rail bracket (not shown) in this example, similarly to the first seat 10. The second sheet 20 has a slide range that comes into contact with the first sheet 10. The second seat 20, like the first seat 10, is a manual seat (manual seat) and has a lever 22 operated by the occupant's hand.

(lever)
The lever 22 is provided so as to be freely displaceable within a range between a lock position for locking the slide of the second seat 20 and a lock release position for releasing the lock (FIGS. 1 to 5). In the present embodiment, the lock position is when the lever 22 is located below as shown by the solid line in FIGS. 1 and 2 and the two-dot chain line in FIGS. In the present example, the lock release position is when the lever 22 is located upward as shown by the solid line in FIGS. That is, when the lower lever 22 is displaced upward, the lock of the slide of the second seat 20 is released, and when the upper lever 22 is displaced downward, the slide of the second seat 20 is locked. The lever 22 may be biased downward, or may not be biased downward.

  The location of the lever 22 is on the side of the second sheet 20 facing the first sheet 10. In the present embodiment, the opposing side is the front side of the second seat 20. The location of the lever 22 is on the front side below the seat cushion 211. The shape of the lever 22 is C-shaped in this example. The lever 22 has a front side 221, a left side 222, and a right side 223.

  The front side 221 is operated by being gripped by the occupant's hand. The front side portion 221 is formed of a rod-like or cylindrical member extending in the left-right direction on the front side. The front side 221 connects the front ends of the left side 222 and the right side 223. Both end portions of the front side portion 221 (near the connection portion with the left side portion 222 and the right side portion 223) are bent upward, and the center portion of the front side portion 221 is closer to the front end of the left side portion 222 and the right side portion 223. Is also located above. Thereby, even if the first sheet 10 and the second sheet 20 approach each other, the front side portion 221 does not substantially contact the center cover portion 141 of the rear cover 14, and the left side portion 222 and the rear cover 14 substantially do not contact each other. , Only the left cover 142 is contacted.

  The left side part 222 and the right side part 223 transmit an input to the front side part 221 by the occupant's hand to a lock mechanism (not shown) that locks the slide of the upper rail 28. The left side 222 and the right side 223 are disposed on the left and right sides of the second seat 20 in the left-right direction of the vehicle. The front ends of the left side 222 and the right side 223 are connected to the front side 221. The rear ends of the left side 222 and the right side 223 are connected to the lock mechanism (not shown). A known configuration can be used for the connection relationship between the left side portion 222 and the right side portion 223 and the lock mechanism, and the configuration of the lock mechanism. The left side part 222 and the right side part 223 are configured by rod-shaped or cylindrical members extending in the front-rear direction.

  Front portions of the left side portion 222 and the right side portion 223 are inclined so as to rise upward toward the front side. It is preferable that the inclination angle of the front part of the left side part 222 is smaller than the inclination angle of the inclined surface (lock release part 13) of the left cover part 142. Then, when the inclined surface (the unlocking portion 13) of the left cover portion 142 comes into contact with the lever 22 in the locked position, the lever 22 is easily displaced from the locked position to the unlocked position by the unlocking portion 13. The inclination angle of the front part of the left side part 222 refers to the smaller one of the angles formed by the direction along the length of the front part of the left side part 222 and the front-back direction of the vehicle.

[behavior]
Referring to FIG. 2 to FIG. 5, the first seat 10 when the first seat 10 is slid rearward in a state where both the first seat 10 and the second seat 20 are located on the front side of the sliding range. And the behavior of the second sheet 20 will be described.

  As shown in FIG. 2, when both the first sheet 10 and the second sheet 20 are located at the positions on the front side of the sliding range, the first sheet 10 is slid backward. First, the lever 12 of the first seat 10 is manually operated to move the lever 12 from the locked position (FIG. 2) to the unlocked position (shown by a solid line in FIG. 3). Thereby, the lock of the slide of the first sheet 10 is released, and the first sheet 10 is in a slidable state. In this state, the first seat 10 is slid backward.

  As shown by the solid line in FIG. 3, the first sheet 10 and the second sheet 20 come into contact by sliding the first sheet 10 backward. That is, the unlocking portion 13 of the first seat 10 (the inclined surface of the left cover portion 142) comes into contact with the left side 222 of the lever 22 of the second seat 20. Then, the lever 22 is displaced from the locked position (two-dot chain line in FIG. 3) to the unlocked position (solid line in FIG. 3). Specifically, as shown by the solid line in FIG. 5, by sliding the front portion of the left side 222 of the lever 22 on the inclined surface (the unlocking portion 13) of the left cover 142, the lever 22 located below Pull up. Thereby, the lock of the slide of the second seat 20 is released, and the second seat 20 becomes slidable. At this time, as shown by the two-dot chain line and the solid line in FIG. 5, the center cover portion 141 and the right cover portion 143 of the rear cover 14 and the front side portion 221 and the right side portion 223 of the lever 22 do not contact each other. In this state, the first sheet 10 is further slid backward.

  As shown by a solid line in FIG. 4, the second seat 20 in a state where the lock of the slide is released slides backward in conjunction with the backward sliding of the first seat 10. Therefore, excessive contact between the first sheet 10 and the second sheet 20 is suppressed.

(Effects)
The vehicle structure 1 according to the first embodiment slides the first seat 10 at the position on the front side of the slide range backward without noticing that the second seat 20 is at the position on the front side of the slide range, Even if the one sheet 10 and the second sheet 20 come into contact with each other, the damage of the first sheet 10 and the second sheet 20 due to the contact can be suppressed. By providing the unlocking portion 13 that displaces the lever 22 of the second sheet 20 from the locked position to the unlocked position when the first sheet 10 comes into contact with the second sheet 20 accompanying the backward sliding of the first sheet 10, When the first sheet 10 and the second sheet 20 come into contact with each other, the slide lock of the second sheet 20 can be released. In particular, the lock release unit 13 is provided on the first sheet 10 on the side facing the second sheet 20, and the lever 22 is provided on the second sheet 20 on the side facing the first sheet 10. The unlocking section 13 can easily displace the lever 22 from the locked position to the unlocked position at the time of contact between the lever 22 and the second sheet 20. Therefore, when the first sheet 10 and the second sheet 20 come into contact with each other, the movement of the second sheet 20 is not restricted, and the second sheet 20 is slid backward with the first sheet 10. Therefore, excessive contact between the first sheet 10 and the second sheet 20 can be suppressed. In addition, since damage caused by contact between the first sheet 10 and the second sheet 20 can be mechanically performed instead of electrically, it is easy to reduce weight, reduce costs, and improve productivity.

  The present invention is not limited to these examples, but is indicated by the appended claims, and is intended to include all modifications within the scope and meaning equivalent to the appended claims.

  For example, the lock release member may be provided not on the left cover but on the right cover, or may be provided on both the left cover and the right cover.

  When the vehicle structure is provided in a front and rear two-row seat type vehicle, the first seat may be a second-row seat (rear seat) and the second seat may be a first-row seat (front seat). In this case, the levers of the first seat are provided on both the front side and the rear side below the first seat. Like the first seat, the levers of the second seat are provided on both the front side and the rear side below the second seat. The unlocking portion of the first seat is provided on the front side below the first seat. The first sheet includes a front cover that covers a lower front side of the first sheet. The front cover has, for example, a left cover portion and a right cover portion having the same configuration as the rear cover 14 in the first embodiment. That is, the left cover has the same inclined surface as the left cover 142 in the first embodiment. This inclined surface constitutes a lock release section.

  When both the first sheet and the second sheet are at the positions on the rear side of the sliding range, the first sheet is moved to the position on the front side. By manually operating the lever on the rear side of the first sheet from the luggage compartment on the rear side of the first sheet, the lock of the slide of the first sheet is released, and the first sheet is slid forward. By sliding the first sheet forward, the first sheet and the second sheet come into contact. At this time, the unlocking portion of the first sheet (the inclined surface of the left cover of the front cover) displaces the lever on the rear side of the second sheet from the locked position to the unlocked position. In this state, when the first sheet is further slid forward, the second sheet in the unlocked state slides forward in conjunction with the forward sliding of the first sheet. According to this example, without noticing that the second sheet is at the position on the rear side of the slide range, for example, the first sheet at the position on the rear side of the slide range is slid forward in an attempt to expand the space of the luggage compartment. Thus, even if the first sheet and the second sheet come into contact with each other, damage to the first sheet and the second sheet due to the contact can be suppressed.

  In addition, the vehicle structure may be provided in a three-row seat type vehicle. In that case, the first sheet may be the first row sheet and the second sheet may be the second row sheet. The first sheet may be a second row sheet and the second sheet may be a third row sheet. The first sheet may be the second row sheet, and the second sheet may be the first row sheet. The first sheet may be a third row sheet and the second sheet may be a second row sheet.
