Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vehicle seat structure.

(Prior Art) Automobile seats are generally slidably attached to the vehicle body via slide rails. In that case, if the seatbelt's belt anchor was fixed to the vehicle body, the length of the seatbelt would need to be adjusted each time the seat was moved, since the way the seatbelt was held would differ depending on the seat position. Problems arise in terms of seatbelt operability, such as the

For this reason, conventional attempts have been made to fix the belt anchor of the seat belt to a top rail of a slide rail that moves integrally with the seat, and to make the belt anchor and the seat slide integrally (for example, , Jitsukai 61-
(See Publication No. 56124).

By the way, when the belt anchor is attached to the slide rail in this way, it is difficult to support the belt load applied to the seat belt on the slide rail side due to the structure or strength of the slide rail. Usually, as disclosed in the above-mentioned known example, a reinforcing rail disposed along the slide rail is provided with an engaging portion with which a belt anchor engages when a belt load is applied, and the reinforcing rail allows the belt load to be I try to support.

However, in the case of a vehicle in which the slide rail is directly fixed to the floor panel side of the vehicle body as in the above-mentioned known example, such a configuration cannot sufficiently serve its purpose because the belt load is smoothly transmitted to the vehicle body side. However, this configuration can be applied to a seat configured such that, for example, a slide rail is attached to a seat frame rotatably attached to the vehicle body, and the seat is attached to this slide rail. In this case, depending on the rigidity of the seat frame, it may be difficult to properly transmit the belt load to the vehicle body.

(Purpose of the invention) The present invention is an attempt to solve the problems pointed out in the above-mentioned section of the prior art.The slide rail on which the seat is attached is attached to the vehicle body side via the seat frame, and the belt anchor is attached to the slide rail. The purpose of this invention is to propose a seat structure that can efficiently transmit the belt load applied to the belt anchor to the vehicle body and improve the supporting capacity of the vehicle seat in which the belt anchor is attached.

(Means for Achieving the Object) The present invention, as a means for achieving the above object, mounts the seat on a slide rail that can be slid in the axial direction, and attaches a belt anchor to the slide rail. In a seat in which a belt anchor is moved together with the seat, one end of the slide rail is fixed to a seat frame rotatably supported in a vertical direction with respect to a vehicle body side member via a support member;
An engaging portion that engages with the belt anchor when a belt load acts on the belt anchor is provided at a position near the support member of the seat frame.

(Function) In the present invention, by the above-mentioned means, the load applied to the belt anchor is transferred so that the engaging portion that supports the belt anchor is located on the seat frame and in the vicinity of the support member that rotatably supports the seat frame toward the vehicle body. Because of the provision of the support member, the signal is efficiently transmitted to the vehicle body through the shortest possible transmission path.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows an automobile seat device equipped with a seat structure according to an embodiment of the present invention. This car has seats 4, 4 provided at the front of the car body 1.
The engine is disposed below the engine, and the upper part of the engine is covered by an engine deck 3, which will be described later, which is formed by bulging a part of a floor deck 2 upward. Further, left and right seats 4, 4 are placed above the engine deck 3 with one side thereof placed on the engine deck 3 via seat frames 40, 40, which will be described later.

Further, belt anchors 10, 10 are provided on the side of each seat frame 40, 40, respectively. A belt hook 11 of a seat belt device 8 disposed on the side of the vehicle body 1 is detachably attached to the belt anchor 10, and the seat belt 9 is connected between the side of the vehicle body and the belt anchor 10. It is stretched in a roughly U-shape. Below, this sheet 4
The supporting structure of the seat 4 will be explained with reference to FIGS. 2 and 3, taking one of the seats 4 as an example.

As shown in FIG. 2, the engine deck 3 is formed by bulging the floor deck 2 upward at a position above the engine (not shown), and its upper surface extends outward in the vehicle width direction from its center. These are sloped surfaces 31, 31 that slope downward in the direction. An opening 32 for engine inspection is formed in this inclined surface 31 over almost the entire area of the inclined surface 31. A lid 33 having a seal 34 (see FIG. 3) around the opening 32 is attached to the opening 32 so that the lid can be opened and closed. An upper edge portion 32 located on the upper side of the opening 32 in the inclination direction.
A seat frame 40, which will be described later, is attached to the seat frame 40 so as to be rotatable in the vertical direction via support members 12, 12, which will be described later.

As shown in FIGS. 2 and 3, the support member 12 includes a fixed side member 13 bolted to the upper end edge 32a of the opening 32 of the engine deck 3 with a mounting bolt 16, and the fixed side member 13. and a movable side member 14 which is supported vertically via a pin 15 so as to be swingable, and one set is disposed on each side of the upper end edge 32a in the width direction. Further, as shown in FIG. 3, the movable side member 14 of the support member 12 is bent into a substantially L-shape so as to easily support a seat frame 40, which will be described later.

The seat frame 40 has a rectangular frame body 41, as shown in FIGS. 2 and 3. This frame body 41 includes a pair of front and rear cross members 44, 45 that extend along the inclined surface 31 of the engine deck 3 and then extend in a substantially horizontal direction, and a pair of cross members 44, 45 extending along the inclined surface 31 of the engine deck 3 in the vehicle width direction of the engine deck 3. It has a proximal end vertical member 42 that connects toward the center, and a distal end vertical member 43 that connects toward the outside in the vehicle width direction. And this frame body 41
connects the proximal vertical member 42 to the supporting members 12,1.
By being joined to the movable member 14 of No. 2, it can be freely rotated in the vertical direction around its base end 41a (see FIG. 3). In FIG. 2, reference numeral 23 denotes a support leg that supports the tip end 41b of the frame 41, and is capable of being raised and lowered. Reference numeral 24 designates a stopper member for removably fixing a position near the tip 41b of the frame 41 to the engine deck 3 side.

Furthermore, this frame 41 has slide rails 51 and 52 attached to the left and right two positions, one near the base end 41a and the other near the tip 41b, respectively, facing in the vehicle length direction. This slide rail 51,5
2 is composed of a lower rail 54 fixed to the frame 41 side and an upper rail 53 that is slidable relative to the lower rail 54, and the seat cushion 5 of the seat 4 is attached to each slide rail. Each upper rail 5 of 51 and 52
3, 53 (not shown).

Furthermore, of the two slide rails 51 and 52, an anchor plate 17 is attached to the upper rail 53 of the slide rail 51 located on the base end 41a side of the frame 41 via a support plate 20 extending in a substantially horizontal direction. The joint is fixed. Furthermore, this anchor plate 17 has a belt anchor 10.
is attached via a mounting bolt 55.

And in this car, this belt anchor 1
In order to efficiently transmit the belt load applied to 0 to the vehicle body, the present invention is applied to curve the lower end 17a of the anchor plate 17 outward in a substantially U-shape and connect it to the hook 18. On the other hand, the upper end 42a of the proximal vertical member 42 disposed close to the anchor plate 17 is curved in a substantially U-shape toward the inside of the opening 32 to form the engaging portion 19. . Then, the hooking portion 18 on the anchor plate 17 side and the engaging portion 19 on the proximal vertical member 42 side are crossed in opposite directions so as to insert the other end into the inside of the curved portion. Assembled in good condition.

Therefore, when a belt load is applied to the belt anchor 10 and the support plate 20 is bent upward, the hooking portion 18 of the anchor plate 17 and the engaging portion 19 of the proximal longitudinal member 42 are bent. They engage with each other in the vertical direction, and the belt load is transmitted to the proximal longitudinal member 42 side. In this case, since the proximal longitudinal member 42 is provided close to the support member 12, the belt load transmitted to the proximal longitudinal member 42 is efficiently transferred to the engine via the supporting member 12. The signal is transmitted to the deck 3 side, that is, to the vehicle body side. Therefore, even though the slide rail 51 to which the anchor plate 17 is attached is attached to the vehicle body via the seat frame 40 (in other words, regardless of the rigidity of the seat frame 40 and the slide rail 51) , a high level of belt load support performance is achieved, which in turn leads to improved vehicle safety.

(Effect of the invention) In the vehicle seat structure of the invention, the seat is attached to a slide rail that can be slid in the axial direction, and a belt anchor is attached to the slide rail so that the belt anchor moves together with the seat. In the seat, one end of the slide rail is fixed to a seat frame that is rotatably supported vertically with respect to a vehicle body side member via a support member, and the slide rail is fixed at a position near the support member of the seat frame. The present invention is characterized in that an engaging portion is provided that engages with the belt anchor when a belt load acts on the belt anchor.

Therefore, according to the vehicle seat structure of the present invention,
The load applied to the belt anchor is efficiently transmitted to the vehicle body through the shortest possible transmission path via the support member that rotatably supports the seat frame toward the vehicle body, and the belt load can be handled at a higher level. This has the practical effect of providing support capacity.
