Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automobile seat device, and in particular,
This invention relates to a seat device in which a seat for a person and a seat for two people are arranged side by side in the vehicle width direction.

(Prior Art) In general, a sliding type seat device among automobile seat devices is configured as a seat device for one person, and is mounted so as to be slidable back and forth on the floor of the vehicle body via a pair of left and right seat sliders.

The end portions of the shoulder belt and lap belt of the seat belt are connected to a belt retractor near the lower end of the center pillar, and the end portion of the seat belt anchor of the seat belt is connected to the slide upper side of the slider.

Rather than connecting the end of the seatbelt anchor to the slide top side as described above, it is better to connect it to the slide rail side on the floor side in terms of impact force locking in the event of a collision. Special Public Service 1976-
Publication No. 36088 discloses that a front leg portion and a rear leg portion are provided in parallel at the front and rear portions of both left and right sides of a seat frame, respectively, and slider units protruding outward are provided on the front and rear leg portions, respectively. , the slider unit is slidably fitted into a slider rail extending in the longitudinal direction of the vehicle body, and a seat belt attachment member is fixed to at least one of the left and right rear leg portions.

(Problem to be solved by the invention) By the way, there is a seat device in which a first seat for one seat and a second seat for two seats are arranged side by side in the vehicle width direction. As for seats, it is difficult to apply the seat device of the above publication to the seat belt of the center seat. That is, the second seat is supported by a pair of seat sliders on the floor on the sides of the bulging tunnel section at the center of the floor, and the center section is formed in a cantilevered manner so as to protrude above the tunnel section. Because of this, the center seat is located closer to the center than the middle seat slider of the seat sliders of the second seat, so the end of the seat belt anchor of the seat belt of the center seat is It will be fixed to the side end portion of the first sheet side.

However, in this case, if a large impact load is applied to the seat belt, since the center seat is cantilevered, there is a need for further improvement in the ability of the seat device including the seat belt to absorb the impact.

(Means for Solving the Problems) The automobile seat device according to the present invention includes a first seat for one person and a second seat for two people, which are arranged in parallel in the width direction of the vehicle.
The second seat has a central seat portion extending above the bulging tunnel with a vertical gap between the second seat and the bulging tunnel portion at the center of the floor panel. At the lower position, place 1 left and right on the floor panel on the side of the bulging tunnel part.
In an automobile seat device supported in a cantilevered manner so as to be slidable in the longitudinal direction via a pair of seat sliders, a seat belt anchor for the center seat is fixed to the side end of the second seat on the first seat side. A rail member is fixed to the side wall of the first seat side of the bulging tunnel portion in the front-rear direction, and the upper end of the connecting member is fixed to the bracket and the lower end is slidably engaged with the rail member. It has stopped.

(Function) Since the automobile seat device according to the present invention is configured as described above, when the position of the second seat is adjusted by sliding it back and forth, the connecting member also slides along the rail member.

In the event of a car collision, a large load is applied to the seat belt from the passenger in the middle seat starting from the end of the second seat on the first seat side, but since the connecting member is locked to the rail member, the seat belt anchor is The large load applied to the bracket is directly received by the rail member, that is, the bulging tunnel portion, via the connecting member.

(Effects of the invention) As explained above, the automobile seat device according to the invention transmits the large load applied to the cantilevered seat belt of the center seat at the time of a collision to the bulging tunnel portion of the floor panel, It can be reliably received by the floor panel.

Furthermore, since the rail member is fixed to the side wall of the bulging tunnel portion, the mounting strength of the seat belt anchor for the center seat can be ensured with a simple structure without sacrificing the space for the passenger's feet.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

As shown in Figures 1 and 2, the seat device installed at the front of the vehicle interior consists of a first seat 1 for one person serving as a driver's seat, and a seat on the left side of this first seat 1 (for those seated on the seat). The vehicle is equipped with a second seat 2 for two people arranged in parallel with each other (based on the number of occupants).

The first seat 1 is attached to the floor panel 4 so as to be slidable back and forth via a pair of left and right seat sliders 3 provided on the lower side thereof, and a shoulder belt 5 of the seat belt of the first seat 1 is attached.
The end of the wrap belt 6 is connected to a belt retractor 8 provided near the lower end of the center pillar so that it can be retracted and unwound, and the end of the seat belt anchor 7 is fixed to the slide top of the left seat slider 3. There is.

The second seat 2 is provided with a passenger seat on the left side and a center seat located between the passenger seat and the driver's seat. It has been extended as follows.

The second seat 2 is slidable back and forth via a floor panel 4 via a pair of left and right seat sliders 3 provided below the passenger seat.
Since the passenger seat seat belt is substantially symmetrical to the driver seat seat belt, the same parts are given the same reference numerals and their explanation will be omitted.

The seat belt for the center seat is composed of a tongue side belt 9 on the left half corresponding to the lap belt 6 and a seat belt anchor 10 on the right half, and the tongue side belt 9 is located between the seat cushion 2a and the seat back 2b. The end of the tongue side belt 9 extends downward from the seat cushion 2 of the second seat 2.
The lower end of the seatbelt anchor 10 is connected to a bracket 13 fixed to the side end of the second seat 2 on the first seat 1 side. is fixed to.

Since the bracket 13 is provided on the rear right end surface of the seat cushion 2a, the seat belt anchor 10 and the tongue side belt 9 are wrapped around the waist of the passenger in the center seat, and the tongue 9a is attached to the buckle 1.
By engaging 0a, the occupant can be restrained from moving forward in the event of a collision.

Here, in order to enable the floor panel 4 to support the large load applied to the seat belt anchor 10 in the event of a collision, the side wall 4a on the driver's seat side of the bulging tunnel 4A is Along the upper part, a rail member 14 having a predetermined length and having a generally groove-shaped cross section is fixed in the front-rear direction by bolts 15 or welding.

Then, the bracket 13 and the rail member 14
The connecting member 16 that connects the two is made up of a connecting plate 17 and a slide fitting 18. The upper end of the connecting plate 17 is strongly fixed to the bracket 13 with a bolt 19, and the lower end is a slide fixed by welding. The metal fitting 18 is slidably engaged with the rail member 14 via a bearing 20.

The slide fitting 18 is a member having a substantially C-shaped cross section. The slide fitting 18 is loosely fitted into the upper half of the rail member 14, and the respective flanges 18a of the rail member 14 are inserted from below the respective flanges 14a of the rail member 14. Tsuba 14
A ball bearing 20 is interposed between the opposing flanges 14a and 18a.

However, the rail member 14 is formed in such a length that it will not come off the slide fitting 18 even when the second seat 2 is slid back and forth to adjust its position, and the rail member 14 is attached parallel to the slider 3. ing.

Note that the connecting member 16 is movable relative to the rail member 14 and is capable of moving relative to the rail member 14 in the event of a collision.
Therefore, as shown in FIG. 4, the rail member 14A is formed to have a 7-shaped cross section, and the connecting member 16A is formed to have an L-shaped cross section. The locked portion 16a of the connecting member 16A is connected to the locking portion 14b by the bearing 20.
The engagement may be made with or without intervening.

In short, the connecting members 16, 16A fixed to the bracket 13 are slidable with respect to the rail members 14, 14A so as not to impede the sliding of the second seat 2 in the front-rear direction, and the connecting members 16, 16A fixed to the bracket 13 are capable of sliding from the seat belt anchor 10 in the event of a collision. It is only necessary that the bracket 13 be reliably locked by the rail members 14, 14A when a large load is applied to it.

Incidentally, as shown in FIG. 5, the lower end of the tongue side belt 9A of the center seat may be connected to a belt retractor 21 provided on the floor panel 4.

In the above configuration, a large load applied to the ends of the tongue side belts 9 and 9A of the seat belts for the center seat of the second seat 2 is supported by the hinge shaft 12 and the belt retractor 21, and the ends of the seat belt anchors 10 are supported by the hinge shaft 12 and the belt retractor 21. The large load applied to the rail member 14, via the bracket 13 and the connecting members 16, 16A,
14A, that is, the bulging tunnel 4A of the floor panel 4
will definitely be supported.

The bracket 13, the connecting members 16, 16A, and the rail members 14, 14A are arranged by utilizing the relatively narrow dead space between the first seat 1 and the second seat 2, so there is no space left for other equipment. There is no sacrifice in leg space for passengers.
