Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support structure for a seat belt buckle device.

[Conventional structure]

Conventionally, a seat belt buckle device for a vehicle has been supported by a buckle stay whose one end is fixed to a floor panel with a single bolt.

However, with this structure, when the bolt loosens due to vibrations that occur during driving and the stay rotates, the buckle moves from its designated position, making it difficult to fasten the seat belt. There were other problems.

On the other hand, in order to solve this problem, if the stay is supported at multiple locations on the floor panel, it is necessary to form as many engagement parts on the floor panel, resulting in a problem that the structure becomes complicated. There is.

[Purpose of the case]

The object of the present invention is to obtain a support structure for a seat belt buckle device that solves the above-mentioned problems.

[Summary of the invention]

The present invention was devised in view of the above, and includes a buckle to which a tongue attached to a seatbelt is removably engaged, and a buckle that supports the buckle and is fixed to a first opening formed in the vehicle body via a bolt. A seatbelt buckle device comprising a buckle stay, the seatbelt comprising a bracket having one end engaged with a second opening formed in the vehicle body and the other end engaged with the buckle stay. This is the support structure for the buckle device.

[Example of the present invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

2 shows a cross section of the vehicle body, in which a driver's seat 6, a center seat 8, and an auxiliary seat 10 are provided on a floor panel 4. The floor panel 4 is formed higher than both side parts 16 and 18 because the center part 12 forms an engine room 14 below. 20,2
Reference numerals 2 designate seat belts for the driver's seat 6 and the auxiliary seat 10, to which tongues 24 and 26 are attached by through rings or the like. Numerals 28 and 30 are seat belt buckle devices configured to engage with the tongues 24 and 26, respectively, and both have substantially the same shape.

The seat belt buckle device 28 for the driver's seat 6 will be explained below.

32 is a buckle with which the tongue 24 is engaged;
is a buckle stay made of sheet metal, one end 36 is provided with the same buckle 32, and the other end 38 is attached to the floor panel 4.
An opening 48 is formed to be fixed to a first opening 42 formed in the inclined portion 40 through a bolt 44 and a nut 46. Reference numeral 50 denotes a rotation prevention bracket made of sheet metal, and one end 52 has an opening 54 through which the bolt 44 is inserted, and claw members 56, 58, 6 for rotation prevention against the other end 38 of the buckle stay 34.
0 is formed, and the other end 62 is provided with a pin 64 that projects downward. Reference numeral 66 denotes a second opening formed near the first opening 42, and is formed so that a seat belt or a buckle device for the center seat 8 can be attached as required. 68
A plug made of synthetic resin is press-fitted into the second opening 66, and a small hole 70 is formed inward from the upper surface of the plug.

The seat belt buckle device 28 has the other end 38 of the buckle stay 34 overlapped with one end 52 of the rotation stopper bracket 50, and the first end 38 formed on the inclined portion 40 of the floor panel 4 by the bolt 44 and nut 46. At the same time as engaging the opening 42, the pin 64 at the other end 62 of the anti-rotation bracket 50 is
Small hole 7 of plug 68 disposed in second opening 66
0.

Therefore, according to the present embodiment, the buckle stay 34 is connected to the bolt 44 and the pawl member 56 of the anti-rotation bracket 50 positioned by the pin 64.
58 and 60, the buckle stay 3 does not rotate, and positioning can be performed easily and reliably. Moreover, since the bracket 50 is constructed separately from the buckle stay 3, the buckle stay 3 can be used without using the bracket 50.
When the buckle 32 is supported by the buckle 32, the second opening 66 becomes an opening for attaching a seat belt for the center seat 8, a buckle device, etc., if necessary.
It has excellent versatility.

[Effects of this invention]

According to the present invention, the buckle stay is held by the first opening and the bracket positioned by the second opening, and the buckle stay can be easily and reliably positioned without rotating. play.

It is also possible to support the buckle only with the buckle stay without using the bracket, and in that case, the second opening can be used as an opening for attaching the seat belt of the adjacent seat or the buckle device, making it highly versatile. be effective.
