Description

[Detailed Description of the Invention] The present invention relates to a vehicle seat device equipped with a seat belt. Usually, a seat belt attached to a vehicle seat device has both base ends fixed to the seat frame of the seat cushion, and one of the base ends fixed to a side end of the seat cushion. Therefore, if a strong external traction force is applied to the seatbelt in the event of a collision, the seat may be damaged due to insufficient strength of the seat frame.
Due to deformation of the slide rail, the sliding function cannot be obtained, and even reinforcing the seat frame is not a basic measure to prevent damage to the slide rail.
This results in a significant increase in the cost of the seat. In addition, as shown in Fig. 1, in the case of a one-door vehicle equipped with a first row seat a and a second row seat b, or in the case of a vehicle further equipped with a third row seat c, the first row seats a, two seats The fastening mechanism at the base end of the seatbelt protruding from the side edge of the seat cushion of row seat B and the seatbelt obstruct the transfer to the rear seats (particularly in the case of second row seats, the height is insufficient). ) becomes
Furthermore, if the base end of the seat belt is fixed to the vehicle body side, it does not affect the seat or the slide mechanism, but it has drawbacks such as interfering with getting on and off the seat.

This invention relates to an invention to eliminate the above-mentioned drawbacks of conventional vehicle seat devices equipped with seat belts, and as stated in the claims of the utility model registration, the present invention relates to a seat frame that forms the framework of the seat cushion. A box-shaped seat stand with a rectangular cross section that is interposed and fixed between the lower side of the vehicle in the width direction and a slide rail that is fixed to the floor panel and allows the seat to slide toward the rear of the vehicle. By providing a base end of the seat belt on the outer surface of the seat stand, the seat and slide mechanism absorb the strong external traction force applied to the seat belt due to the rigid support force of the seat stand. For vehicles that prevents damage to the seat belt, secures the height of the seat cushion with a seat stand, and has a fixing mechanism for the base end of the seat belt located inside the side edges of the seat cushion to improve ingress and egress performance. The point is that it provides a seat device.

The present invention has the above-mentioned configuration, and a box-shaped seat stand with a rectangular cross section that is interposed and fixed between the seat frame and the slide rail is capable of generating a strong external traction force that is applied to the seat belt in the event of a collision, etc. The rigid support force prevents deformation and damage to the seat and slide rail without special reinforcement of the seat frame and slide rail, and the seat stand This makes the seat cushion higher, and the box-shaped seat stand with a rectangular cross section that is interposed and fixed between the seat frame and the slide rail allows it to be raised moderately from the floor, pillars on the side of the vehicle, etc. Because they are separated from each other, they have the advantage of not interfering with getting on and off the rear seats.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
An embodiment of the present invention is shown in FIGS. 2 to 4, in which 1 is a seat cushion, 2 is a seat back disposed at the rear of the seat cushion 1, and the seat back 2 has an angle adjustment lever 13,
Walk-in lever 14 and forward-folding lever 1
By operating 5 in the direction of the arrow, the seat can be reclined and folded onto the seat cushion 1 shown by the two-dot chain line.

Further, in this embodiment, a box-shaped seat stand 3 having a rectangular cross section is extended in the longitudinal direction of the vehicle and fixed to the seat frame 4 side as shown in FIG. The upper rail 5a is fixed along the lower surface with bolts, nuts, welding, etc., and the lower rail 5b is combined with the upper rail 5a to form the slide rail 5.
Fix the front and rear of b with brackets 6 and 7 to fix the floor 20,
That is, the sheet is disposed on the floor 20 by being fixed to the floor panel with bolts or the like.

The seat stand 3 has a seat frame 4 of the seat cushion 1 on the upper side as shown in FIG.
mounting nuts 3a, 3a for fixing to the seat belt 10, an insertion recess 3b for the seat belt 10 on the upper rear side of the outer surface,
Mounting nuts 3c, 3 for mounting the adjuster 8 for reclining at the front and rear of the insertion recess 3b.
c, and an inwardly inclined surface 3f (see FIG. 4) on the lower side of the insertion recess 3b is provided with an anchor hole 3d for the proximal end of the seat belt 10, that is, the fastening fitting 10a, and the seat stand 3 has the following features: As shown in the figure, it is formed into a box shape of sheet metal or the like to increase rigidity, and its upper surface side is aligned with the lower side of the seat frame 4 at the side of the seat cushion 1, and the mounting nuts 3a, 3
a. It is firmly fixed with a bolt, and the adjuster 8 attached to the seat side with the mounting nuts 3c, 3c and a bolt is fixed on the outside of the insertion recess 3b through which the seat belt 10 is inserted. It has a structure in which the seat is firmly placed on the upper side.

Further, the base end portion of the seat belt 10, that is, the fastening fitting 10a, is firmly fixed to the hole 3d provided in the inclined surface 3f as described above with the bolt 11, and the fastening device is attached to the side of the seat cushion 1. The seatbelt 10 is inserted into the insertion recess 3b whose outside is covered with the adjuster 8, and extends over the seat cushion 1. The structure is such that the base end side of the seat belt 10 does not protrude outward from the outer surface of the seat stand 3, and if necessary, a storage case 12 for the seat belt 10 can be provided as shown in the figure.

Note that 13a, 13b, and 13c shown in FIG. 2 are seat slide adjuster release levers that are operated in the direction of the arrow, and the specific mechanisms for releasing the slide rail 5 by these levers are known in the art. Since it can be implemented by means, detailed explanation thereof will be omitted.

Further, in the above embodiment, only one side of the seat cushion has been described, but a similar structure is provided on both sides of the seat cushion.

Since the illustrated embodiment has the above-described configuration, the seat can be operated to recline the seat back 2 and fold it onto the seat cushion 1, and also to slide the entire seat in the longitudinal direction of the vehicle body. Furthermore, a box-shaped seat stand 3 oriented in the longitudinal direction of the vehicle body is firmly fixed to the lower side of the seat cushion 1 by a seat frame 4 and an adjuster 8. Rail 5 is installed,
Since the slide rail 5 is fixedly installed on the floor 20 side, the strong rigid support force of the seat stand 3 can sufficiently absorb the strong external traction force applied to the seat belt 10 in the event of a collision, etc. The rigidity of the seat stand 3 prevents deformation and damage to the seat and slide rail 5, making it unnecessary to provide a reinforcing structure for the seat and slide rail, which is economical. is higher, and the base end of the seat belt 10, that is, the fastening mechanism of the fastening fitting 10a is disposed larger inside than the side end of the seat cushion 1, and the seat belt 10 is inserted into the insertion hole 3b. By inserting the seat through the seat, it is prevented from hanging down, and sufficient room for getting on and off is ensured.

Note that, due to the above-mentioned clearance for getting on and off, it is also possible to attach the storage case 12 for the seat belt 10 below the adjuster 8.
