Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a hinge bracket used in a flip-up seat of a vehicle.

BACKGROUND ART This type of hinge bracket consists of a floor side bracket and a seat side bracket connected to each other by a pin.
and a helper spring assembled to enable the flip-up seat of the vehicle to be easily flipped up, the helper spring having one end receiving the seat-side bracket, and
Since the other end is fixed to the floor bracket with a straight end, there is a gap between the straight end and the clip, which causes abnormal noises every time the seat is flipped up, and when the vehicle is running. The vibrations caused an abnormal noise, which caused discomfort to the passengers.

Purpose/Problem of the invention The purpose/problem of this invention is to create a flip-up seat that enables the fixed end of the helper spring to be fixed without any gaps and prevents the occurrence of abnormal noise due to play in the fixed end of the helper spring. Provides the hinge bracket used.

Description of specific examples Hereinafter, specific examples of the hinge bracket used in the flip-up seat of this invention will be explained.
This will be explained with reference to the drawings.

Figures 1 and 2 show a specific example 10 of the hinge bracket used in the flip-up seat of this invention applied to the rear seat of a light van.

This hinge bracket 10 includes a floor side bracket 11, a seat side bracket 12, and a helper bracket 11.
It was assembled with a spring 13 and a clip 17.

The floor side bracket 11 is made of an adapted shape to be fixedly attached to the floor (not shown), while the seat side bracket 12
is connected to its floor side bracket 1 via pin 14.
1, the cushion is rotatably connected to the seat cushion of the rear seat.
The front part of the frame (not shown) has been fixedly mounted and the rear seat has been made flipable with respect to the floor.

The helper spring 13 is connected to the pin 14
The coil spring was arranged around the seat and had a seat-side bracket receiver at one end 15 and an arcuate bent end at the other end 16.

The clip 17 is manufactured in the shape shown in FIG. 2, and as shown in FIG. I stopped it on the floor side bracket 11.

Therefore, the hinge bracket 10 is
The seat-side brackets 12 are installed in advance on the cushion frame at an appropriate distance in the left-right direction in front of the lower surface of the seat cushion. It is assembled.

Then, the floor side bracket 11 is screwed to the floor, and the hinge bracket 10
installs the rear seat on the floor.

In this hinge bracket 10 with the rear seat installed on the floor in this way, the helper spring 13 elastically compresses and deforms the arcuate bent end 16 in the direction of expanding with the clip 17. is fixed to the floor side bracket 11, and as a result, the arcuate bent end 1
A gap, so-called play, between the rear seat 6 and its clip 17 is eliminated, and accordingly, the raising of the rear seat and the generation of abnormal noise due to vibration are prevented.

As is clear from the specific examples of this invention described above with reference to the drawings, the contents of this invention are clear to those with ordinary knowledge in the technical field to which this invention pertains. In order to achieve the task of the invention, it is essential for the creation of the invention and is the nature of the invention, which originates from the technical essence of the invention, and which can be easily recognized objectively as incorporating it. materialized.

Conveniences and Benefits of the Invention As can be understood from the above, the hinge bracket used in the flip-up seat of this invention includes a floor-side bracket that is fixedly attached to the floor, and a hinge that rotates to the floor-side bracket via a pin. a seat-side bracket arranged about the pin and having a seat-side bracket receiving end at one end; , includes a helper spring each having an arcuate bent end at the other end, and a clip that elastically crushes and deforms the arcuate bent end of the helper spring in the direction of expanding and fixes it to the floor side bracket. In the hinge bracket used in the flip-up seat of this invention, when the arcuate bent end of the helper spring is fixed to the floor side bracket with its clip, there is a gap between the arcuate bent end and the clip. In other words, play is eliminated, and the occurrence of abnormal noise due to the seat flipping up or vibrations when the vehicle is running is prevented, and the discomfort caused by the abnormal noise to the occupant is eliminated, thereby improving riding comfort.
