Abstract

PROBLEM TO BE SOLVED: To avoid spread-deformation of a wire hook, to fasten slipping a bolt with the wire hook, to easily do an assembling work, and to firmly assemble a rear seat to a body floor when the bolt is fastened by force and forcible power is acted on a rear seat even when a thin wire is used for the U-shaped wire hook. SOLUTION: A frame main body 11 has a U-shaped wire hook 16. The wire hook 16 curves a U-shaped curving side of a straight wire section to form a mountain projection 19. A bolt space 20 is determined at a U-shaped curving section 17 by narrowing a space between the straight wire sections 8, 8 by the mountain projection 19.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rear seat frame used for a rear seat of an automobile.

[0002]

BACKGROUND ART Normally, the rear seat of a car is
Having a plurality of U-shaped wire hooks on the frame, and
The wire hook is fixed to the body floor with bolts. When the U-shaped wire hook is forcibly bolted or when excessive force is applied to the rear seat, the U-shaped wire hook is
There was a risk that the wire portion would be expanded and deformed and come off from the bolt. Therefore, the U-shaped wire hook requires a certain amount of thick wire, which has a negative effect on weight reduction and installation work.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to spread a deformation of a U-shaped wire hook when the wire hook is forcibly bolted or an excessive force is applied to the rear seat even if a thin wire is used. It can be avoided and the wire hook can be retained on the bolt, and the installation work can be simplified,
Another object of the present invention is to provide a rear seat frame capable of firmly mounting the rear seat on a body floor.

[0004]

Means corresponding to the object and the operation thereof
The frame body has a U-shaped wire hook, and the wire hook
The bent side is bent into a ridge, and the ridge is narrowed between the straight wires, and the area of the washer pinched by the head of the bolt is increased,
Also, the bolt can be positioned.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a rear seat frame of the present invention will be described based on a specific example shown and shown in FIGS. 1 to 3. FIG. 1 to FIG. 3 show a rear seat of a passenger car. Example 10 of the rear seat frame of the present invention as applied to a cushion is shown, and in the rear seat frame 10, ie, in the rear seat cushion frame 10, the frame body 11 includes a wire. From the frame front 12, the frame rear 13, and the left and right frame sides 14, 1
4 and welded the left and right U-shaped wire hooks 16 and 16 to the frame front 12 and the U-shaped wire hook 16 to the frame rear 13 respectively. The wire hooks 16, 16, 16 bend the U-bend of one of the straight wire portions 18, 18 into a ridge 19, and at the ridge 19, the straight wire portion 18 is bent. , 18 are narrowed to define a bolt space 20 in the U-shaped bent portion 17.

In this rear seat cushion frame 10, reference numerals 15, 15, 15 are vertical connecting wires.

Therefore, the wire hooks 16, 1
6 and 16 are narrowed between the U-shaped bent sides of the straight wire portions 18 and 18 by the ridge bending 19 and the contact area of the washer 32 pinched by the head 31 of the bolt 30 is increased. When the wire hooks 16, 16, 16 are forcibly tightened to the body floor of the passenger car by the bolts 30 or when an excessive force is applied to the rear seat, that is, the rear seat cushion. Wire hooks 16, 16, 16
Is prevented from spreading and deforming the straight wire portions 18, 18 apart from each other, and is securely stopped by the bolt 30. As such, the wire hooks 16, 16, 16 firmly mount the rear seat cushion to the body floor of the passenger car. Further, in the wire hooks 16, 16, 16, the bolt space 20 as a bolt hole is determined in the U-shaped bent portion 17 by the push-in bending 19, so that the bolt 30 can be easily positioned and installed. Work becomes easier. Further, the wire hooks 16 and 16 are prevented from spreading and deforming even if a thin wire is used, the weight is reduced, and the installation workability is improved.

The wire hook 16 is applicable to a rear seat back of the rear seat.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, one skilled in the art to which the present invention pertains will appreciate the subject matter of the present invention. Is the nature of the invention (na
), and are readily embodied in other aspects that are objectively recognized as including them. Of course, the content of the present invention corresponds to the subject of the invention (be commensu).
rate with) and essential for the invention.

[0010]

As will be appreciated from the foregoing, the rear seat frame of the present invention has a frame body with a U-shaped wire hook, and the wire hook is formed of a straight wire portion thereof. Since the U-shaped bent side is bent into a ridge and the ridge is narrowed to define a bolt space in the U-shaped portion by narrowing the straight wire portion.・ When the hook is clamped by the head of the bolt to increase the contact area of the washer and the wire hook is forcibly tightened to the car body floor with the bolt or when excessive force is applied to the rear seat The wire hook is prevented from spreading and deforming the straight wire portions away from each other, and is securely retained by the bolt, and A sheet is mounted firmly to the body floor of the motor vehicle, also the wire
The hook has its bolt space defined in its U-shaped bend by its pushing and bending, so that the bolt can be easily positioned and the installation work can be simplified, and the wire and the wire can be easily fixed.
The hook is prevented from spreading and deforming even when a thin wire is used, the weight is reduced, and the installation workability is improved. As a result, the hook is very useful and practical for a rear seat of an automobile.
