Abstract

PURPOSE:To increase the strength of a seat frame and aim at making the seat frame lightweight, by securing a retractor in the lower section of a reinforcement laid between the right and left of the rear lower surface of a rectangular frame body, and by making webbing extendible and retractable along the reinforcement as a guide. CONSTITUTION:A slidable adjuster 2 is fixed to the lower surface of a channel- like cross-sectioned shape frame body 1 set in a rectangular shape, and a closed cross-section shape reinforcement 3 is disposed and secured between the slidable adjuster 2 and the frame body 1. Further, a retractor 4 is secured by means of bolts to the lower surface of one of the side sections of the reinforcement 3, and is wound thereon with webbing 6. An opening is formed in the lower surface of the reinforcement 3 to allow the webbing to be inserted into and removed from the inside of the reinforcement 3. With this arrangement, the frame body 1 is subjected to a lateral load due to a load exerted to the webbing 6, but since the frame body 1 is reinforced by the reinforcement 3, it is possible to aim at making the frame body lightweight.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a seat frame provided with a seat belt device.

[Prior art and problems to be solved by the present invention] As a conventional seat frame, for example, the actual opening shaft 57-
There is a publication No. 13054.

According to this structure, if a large load (for example, 1360 kg) is applied to the webbing, the guide or the hole in the frame may be bent by the load, and no measures are taken against this. Another element that receives such a load is the seat frame itself, which requires a strength greater than a predetermined value, which may lead to an increase in board thickness and weight.

SUMMARY OF THE INVENTION In view of the conventional example, an object of the present invention is to substantially increase the strength of a seat frame and to provide a lightweight frame.

[Structure of the invention]

In order to achieve such an object, the present invention installs a reinforcement between the left and right sides on the rear lower surface of a rectangular frame main body, secures a retractor at the bottom of the reinforcement, and uses the reinforcement as a guide to move the webbing in the left and right direction. The seat frame is designed to be able to move forward and backward.

[For production]

Therefore, if a large load is applied to the webbing, all of it will be received by the reinforcement, and since the seat frame can be made thinner and weaker, it will be lighter even if it is added to or subtracted from the additional reinforcement.

〔Example〕

Next, one embodiment of the present invention will be described using the drawings.

In the figure, 1 is a frame body fixed in a rectangular shape with a channel-shaped cross section, 2 is a slide adjuster fixed to the lower surface of the frame body 1, and 3 is between the lower surface of the frame body 1 and the upper surface of the slide adjuster 2. A reinforcement with a closed cross section is inserted and fixed, 4 is a tractor fixed with a bolt 5 on the lower surface of one side of the reinforcement 3, 6 is a webbing wrapped around the retractor 4, and 7 is a frame body A spring 1 is suspended, a pad 8 is supported on the spring 7 and the frame body 1, a pad 9 is fixed to a skin (not shown) covering the pad 8, and a webbing 6 is attached.
It is a through anchor plate that guides the There is an opening 10 on the lower surface of the reinforcement 3, and the structure is such that the webbing 6 can be inserted into and removed from the inside of the reinforcement 3. In addition, 11
12 is a seat cushion, and 12 is a seat bank.

The reinforcement 3 may have a structure in which the opening faces downward in the cross section C.

With this configuration, the frame body 1 will receive a lateral load due to the load applied to the webbing 6 in the event of a collision, but with the reinforcement 3, this frame body 1
As a result, the weight of the frame body 1 can be reduced.

〔effect〕

As described above, according to the present invention, the frame body can be made lighter even after adding and subtracting the amount of reinforcement, resulting in improved fuel efficiency.
