Description

  The present invention relates to a vehicle seat device in which a seat is supported on a vehicle body so as to be slidable back and forth.

  A general vehicle seat device supports a pair of support legs provided on the left and right sides of a lower part of a seat so as to be slidable back and forth by a pair of left and right slide rails provided on a floor. The pair of left and right slide rails are arranged at an interval on the upper surface of the floor. Since there is a slide rail on the floor, even if the door is opened, luggage cannot be placed under the seat from the door opening side. For this reason, when placing a load in the space under the seat, the load is inserted between the two slide rails from the front of the seat. This is troublesome to put the luggage. Conventionally, for example, when a driver brings luggage into a passenger compartment, it is generally performed to place the luggage in a rear seat or a passenger seat.

  Incidentally, in recent years, a technique has been developed in which a support leg is not provided at the lower portion of the seat. As such a vehicle seat device, for example, a technique described in Patent Document 1 below is known. The vehicular seat device known from Patent Document 1 hangs a seat on a pair of left and right slide rails provided on a roof of a vehicle body.

  However, in the vehicle seat device known from Patent Document 1, since the seat and the load applied to the seat are supported only by the roof, it is necessary to further increase the strength of the roof. This is not a good idea for reducing the weight and cost of the vehicle. In particular, the slide rail located on the vehicle width center side is exposed from the roof to the vehicle compartment. For this reason, there is room for improvement in securing the appearance of the passenger compartment.

JP 2002-104040 A

  It is an object of the present invention to provide a technology that can easily place a luggage under a seat from the door opening side of a vehicle while ensuring the appearance of a passenger compartment.

In the invention according to claim 1, in the vehicle seat device including the slide device that supports the seat so as to be slidable in the front-rear direction of the vehicle body,
The seat has a support leg provided on the center side in the vehicle width direction, and a hanger provided on the outer side in the vehicle width direction,
The slide device is provided with a first slide rail that supports the support leg on the floor of the vehicle body so as to be slidable in the vehicle longitudinal direction, and is provided on the outer side in the vehicle width direction with respect to the first slide rail. A vehicle seat device comprising: a second slide rail that is slidably supported on a roof of a vehicle body in a longitudinal direction of the vehicle body.

  The invention according to claim 2 is characterized in that the hanger includes an anchor that supports a part of a seat belt for the seat.

  The invention according to claim 3 is characterized in that the hanger includes a side airbag for protecting an occupant seated on the seat.

In the invention which concerns on Claim 1, the load applied to a sheet | seat and a sheet | seat can be distributed and supported by a floor and a roof via a support leg and a hanger. For this reason, the strength of the roof can be reduced as compared with the case where the seat and the load applied to the seat are supported only by the roof.
Furthermore, it is not necessary to arrange a slide rail on the center side of the vehicle width in the roof. For this reason, the appearance of the passenger compartment can be ensured.
Furthermore, it is not necessary to arrange slide rails on the floor outside in the vehicle width direction. For this reason, when the door is opened, luggage such as baggage can be easily placed under the seat from the door opening side of the vehicle. In this way, the empty space under the seat can be effectively utilized.

  In the invention which concerns on Claim 2, the hanger is equipped with the anchor which supports a part of seat belt. When the seat slides in the longitudinal direction of the vehicle body, the anchor also slides in the longitudinal direction of the vehicle body together with the hanger. For this reason, the relative position of the anchor with respect to the sheet does not change. The posture when the occupant seated on the seat attaches or detaches the seat belt may always be the same. Therefore, the seat belt can be attached and detached with a comfortable posture at all times.

  In the invention which concerns on Claim 3, the hanger is equipped with the side airbag for protecting the passenger | crew who is seated on the seat. For this reason, the relative position of the side airbag with respect to the seat does not change regardless of the position of the seat in the front-rear direction with respect to the vehicle body. When the side airbag is inflated and deployed, the occupant seated on the seat can be sufficiently effectively protected by the side airbag.

The hanger 38 is a substantially vertical and elongated flat plate-like member located on the rear side portion of the seat cushion frame 35 and preferably extends upward along the seat back 33 in a standing state. The hanger 38 is generally adjacent to the inner surface of the center pillar 22 when the sheet 31F is located at the rearmost position.

  The slide device 41 includes a pair of left and right slide rails 42L and 42R, left and right sliders 43L and 43R, and left and right slide lock mechanisms 44L and 44R. Hereinafter, the pair of left and right slide rails 42L and 42R will be described as “first and second slide rails 42L and 42R” as appropriate. Further, the left and right slide lock mechanisms 44L and 44R will be described as “first and second slide lock mechanisms 44L and 44R” as appropriate.

  The first and second slide rails 42L and 42R are elongated members in the front-rear direction of the vehicle body 20, and are arranged in parallel to each other. The first slide rail 42L is disposed on the center side in the vehicle width direction with respect to the seat 31F, and is attached to the upper surface of the floor 26 of the vehicle body 20. The second slide rail 42R is disposed on the outer side in the vehicle width direction with respect to the seat 31F, and is attached to a portion of the roof 25 of the vehicle body 20 on the outer side in the vehicle width direction or the roof rail 24. The second slide rail 42R is generally covered with an interior member so that it is difficult to see from the interior of the vehicle compartment 11.

  More specifically, a first slider 43 </ b> L is provided at the lower end portion of the support leg 37. A second slider 43R is provided at the upper end of the hanger 38. The first slide rail 42L supports the first slider 43L on the floor 26 so as to be slidable in the longitudinal direction of the vehicle body. The second slide rail 42R is provided on the outer side in the vehicle width direction than the first slide rail 42L, and supports the second slider 43R on the roof 25 so as to be slidable in the longitudinal direction of the vehicle body. These slide rails 42L, 42R and sliders 43L, 43R have, for example, a well-known configuration that is employed in ordinary passenger cars.

  The first slide lock mechanism 44L locks and unlocks the first slider 43L with respect to the first slide rail 42L. The first slide lock mechanism 44L is unlocked by the lock operation lever 45. The second slide lock mechanism 44R locks and unlocks the second slider 43R with respect to the second slide rail 42R. The second slide lock mechanism 44R is connected to the lock operation lever 45 via a wire cable 46 (see FIG. 3).

  The first and second slide lock mechanisms 44L and 44R have, for example, a well-known configuration that is employed in ordinary passenger cars. For example, each of the slide lock mechanisms 44L and 44R includes a large number of locking holes formed in the vehicle body front-rear direction of the slide rails 42L and 42R and lock claws provided on the sliders 43L and 43R. When the lock claw is engaged with a part of these engagement holes, the sliders 43L and 43R are locked with respect to the slide rails 42L and 42R.

  By unlocking the lock operation lever 45, the sliders 43L and 43R are unlocked with respect to the slide rails 42L and 42R. That is, as in the conventional case, the occupant Mn unlocks the lock operation lever 45 to unlock the first and second slide lock mechanisms 44L and 44R, and the front and rear of the seat 31F with respect to the slide rails 42L and 42R. The slide position can be adjusted. Thereafter, when the hand is released from the lock operation lever 45, the first and second slide lock mechanisms 44L and 44R are again locked by an urging force of a return spring (not shown).

  As described above, one of the first and second slide rails 42L and 42R for supporting the slide position of the seat 31F in an adjustable manner is provided on the floor 26, and the other is provided on the roof 25. The front / rear slide position of the seat 31F can be adjusted by an operation similar to a normal slide operation.

  The above description is summarized as follows. FIG. 4 is a diagram illustrating an operation in a state where the vehicle 10 is viewed from the outside. In FIG. 4, the door 27 (see FIG. 1) adjacent to the seat 31F is omitted in order to facilitate understanding of the drawing.

  As shown in FIGS. 1 to 4, the slide device 41 includes a first slide rail 42 </ b> L that supports the support leg 37 on the floor 26 so as to be slidable in the longitudinal direction of the vehicle body, and a vehicle width direction relative to the first slide rail 42 </ b> L. A second slide rail 42 </ b> R that is provided outside and supports the hanger 38 on the roof 25 so as to be slidable in the longitudinal direction of the vehicle body.

  For this reason, the load applied to the seat 31 </ b> F and the seat 31 </ b> F can be distributed and supported by the floor 26 and the roof 25 via the support legs 37 and the hangers 38. For this reason, compared with the case where the load applied to the seat 31F and the seat 31F is supported only by the roof 25, the strength of the roof 25 can be reduced. Furthermore, it is not necessary to arrange a slide rail on the center side of the vehicle width in the roof 25. For this reason, the appearance of the compartment 11 can be ensured.

  Furthermore, as shown in FIG. 4, it is not necessary to arrange a slide rail on the floor 26 on the outer side in the vehicle width direction. For this reason, when the door 27 (the side door 27 shown in FIG. 1) is opened, the luggage Ba such as baggage can be easily placed under the seat 31F from the door opening 28 side of the vehicle 10. Thus, the empty space Sp under the sheet 31F can be effectively utilized.

  Further, the hanger 38 is provided with a second lock operation lever (not shown) that functions in the same manner as the lock operation lever 45, a lock release switch, and the like. By operating these, the occupant does not have to enter the vehicle. The seat 31F can be slid back and forth from the outside of the vehicle with the door 27 opened. By attaching the second lock operation lever (lock release means) to the hanger 38, the hanger 38 can be moved while the slide lock of the seat 31F is released, and the operability of the seat slide operation is improved.

  In the past, when a wheelchair user moved from the wheelchair Wc to the seat 31F, the wheelchair Wc on which the user was riding was folded and lifted to the front of the body, and the wheelchair Wc was drawn into the passenger compartment 11. On the other hand, in the present invention, the folded wheelchair Wc can be passed under the seat 31F and pulled into the foot of the rear seat 31R. By doing in this way, it can prevent soiling clothes with the dust and mud which adhered to the wheel of wheelchair Wc.

In this state, the position of the hanger 38 substantially matches the center pillar 22. Further, the hanger 38 is provided on the seat 31F so as to be positioned substantially beside or slightly behind the upper body of the occupant Mn seated on the seat 31F.

  As shown in FIG. 1, the tongue 56 removed from the buckle 57 is located in the vicinity of the upper anchor 53. The occupant Mn (see FIG. 5) sitting on the seat 31 </ b> F can extend the one hand to the tongue 56, pull it out from the retractor 52, and attach it to the buckle 57. A state in which the occupant Mn wears the seat belt 51 is shown in FIG.

  Thereafter, when the side portion of the vehicle 10 receives an impact force of a certain level or more, the side airbag device 60 detects the impact force with an impact detection sensor (not shown), and according to the sensor signal, FIG. The inflator 61 shown in FIG. 2 generates gas and supplies this gas to the side airbag 62. As a result, as shown in FIG. 5, the side airbag 62 is inflated and deployed between the inner surface of the vehicle body 20 and the occupant Mn to sufficiently protect the occupant.

  FIGS. 6A and 6B show a state when the seat 31F is in the front position with respect to the slide rails 42L and 42R, where FIG. 6A is a side view and FIG. 6B is a top view. In this state, the hanger 38 is located in front of the center pillar 22. That is, the hanger 38 is at a position away from the center pillar 22.
