Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a support structure for a seatbelt buckle of a seatbelt device applied to, for example, a cab-over type automobile.

(Prior Art) In general, in cab-over type trucks and one-box type automobiles, a service hole cover for opening and closing the service hole is pivotally mounted on a floor on which a service hole is formed, so as to be able to swing freely.
A front seat is placed on the service hole cover, and a seatbelt anchor is fixed to the service hole cover, and a seatbelt buckle is supported on the anchor via webbing.

By the way, if a large load is applied to the seat belt anchor fixed to the service hole cover as described above, it may be difficult for the service hole cover alone to absorb the load.

Therefore, conventionally, as disclosed in, for example, Japanese Utility Model Publication No. 54-31449 and schematically shown in FIG. 4, a long hole B extending in the longitudinal direction of the vehicle body is formed in the service hole cover A. A bracket C is attached to the upper part of the cover A on the side of the hole B, and a hook D, which extends vertically through the elongated hole B, is supported on the bracket C so as to be freely swingable via an axis E. A seat belt anchor F is fixed to the upper end of the hook D, and the seat belt buckle is supported by the anchor F via webbing. A support member G is provided with which the hook D engages, and normally the service hole cover A can be freely opened and closed, and the hook D is moved as shown in the figure only when a predetermined tensile load is applied to the seat belt anchor F. The hook D is latched onto the support member G by swinging around an axis E.

(Problems to be solved by the invention) By the way, in the above seat belt buckle support structure, it is necessary to assemble the bracket C, hook D, etc. to the service hole cover A.
It takes time and effort to assemble, and depending on the direction of the load acting on the seat belt anchor F, there may be cases where the hook D does not hook onto the support member G.

This invention was developed in view of the above circumstances.
The purpose is to use an extremely simple configuration,
To provide a support structure for a seat belt buckle, which allows a vehicle body stationary member to reliably receive the load acting on the seat belt, and allows the service hole cover to be freely opened and closed.

(Means for solving the problem) However, the present invention has two service holes on the floor.
In an automobile in which a service hole cover 3 for opening and closing the service hole 2 is swingably supported on the floor, a through hole 33 is formed in the service hole cover 3, and a through hole 33 is formed in the seat belt buckle 5. A stay 6 is provided, the stay 6 is inserted from the vehicle interior to the exterior of the vehicle interior through the through hole 33, and the insertion end thereof is pivotally connected to the vehicle body side stationary member 7, and the stay 6 is connected to the seat belt buckle of the stay 6. 5 side is made to protrude from the service hole cover 3 over a length that allows the opening operation of the cover 3 into the vehicle interior.

(Function) According to the present invention, the seat belt buckle 5
When a tensile load is applied to the vehicle body side stationary member 7, the load can be received by the vehicle body side stationary member 7, and the seat belt buckle 5 and the stay 6 do not pose any obstruction when the service hole cover 3 is opened or closed. There is no such thing.

(Example) A seatbelt buckle support structure according to the present invention will be described below with reference to an example shown in the drawings.

In the figure, reference numeral 1 denotes a floor panel, and the rear part of the floor panel 1 is bulged out one step higher than the front part to form a sheet mounting part 11 which is one step higher than the general surface of the floor panel 1. A diagonally rising side wall 12 is integrally formed at the rear end of the sheet placing portion 11 in the floor panel 1, and the upper end of the side wall 12 is connected to a cross member 13.

A service hole 2 for performing maintenance and inspection of the engine, etc. is formed in the floor panel 1 from the seat mounting portion 11 to the side wall 12, and a service hole cover 3 for opening and closing the service hole 2 is hinged. It is pivotally connected to the cross member 13 via a member 30.

The service hole cover 3 shown in the figure consists of a front cover part 31 that covers the service hole 2 on the side of the sheet placement section 11 and a rear cover part 32 that covers the service hole 2 on the side wall 12 side. The seat cushion 4 is attached onto the front cover part 31 while the rear end of the seat cushion 32 is pivotally connected to the cross member 13 by the hinge member 30 described above.

Therefore, in the embodiment shown in the figures, a through hole 33 is formed in the rear cover part 32 of the service hole cover 3, and a stay 6 is formed in the seat belt buckle 5 that receives a tongue plate (not shown) of the seat belt device. A bowl-shaped seal rubber 61 covering the through hole 33 is inserted into the stay 6, and a connecting fitting 63 having a bolt insertion hole 62 is fixed to the free end of the stay 6.
A length L that extends the free end of the stay 6 from the vehicle interior through the through hole 33 to the exterior of the vehicle interior, and projects further into the vehicle interior than the service hole cover 3 of the stay 6.
is set to be longer than the length that allows the cover 3 to be opened.

On the other hand, a support member 7 consisting of a rod with a circular cross section is disposed outside the vehicle interior near the through hole 33 in the vehicle width direction, and its both ends are attached to a stationary member (not shown) on the vehicle body side such as a side member. At the same time, a bracket 8 is attached to the support member 7 so as to be freely rotatable, and the stay 6 is connected to the bracket 8.

Specifically, the bracket 8 is formed of a curved bracket main body 81 wound around the outer periphery of the support member 7 and a pair of opposing clamping pieces 83, 83 each having a through hole 82. After fitting the main body 81 onto the outer periphery of the support member 7, the connecting fitting 63 is inserted between the holding pieces 83, 83.
At the same time, insert the bolt 84 into the clamping piece 8.
It is inserted into the bolt insertion hole 62 of the connecting fitting 63 through the through hole 82 of No. 3, 83, and the nut 8 is inserted into the insertion end.
5, the stay 6 is supported by the support member 7 via the bracket 8 so as to be freely swingable.

The present invention has the above structure, and when a large tensile load is applied to the seat belt buckle 5 in the forward direction as shown by arrow X in FIG. 1, the load on the seat belt buckle 5 is , it is reliably received by the support member 7 via the stay 6, in other words, by the stationary member on the vehicle body side.

On the other hand, when the service hole 2 is opened and the engine is inspected from inside the passenger compartment, the buckle 5 and the buckle 5 are The stay 6 that supports the swings clockwise in FIG. 1 and does not impede the swing of the service hole cover 3. Therefore, as shown by the two-dot chain line in FIG. 3 can be swung to the open position.

(Effects of the invention) As described above, the present invention provides an automobile in which a service hole 2 is formed in a floor, and a service hole cover 3 for opening and closing the service hole 2 is supported on the floor in a freely swinging manner. A through hole 33 is formed in the cover 3, and a stay 6 is provided in the seat belt buckle 5, and the stay 6 is inserted from the vehicle interior to the exterior of the vehicle interior through the through hole 33, and the insertion end is fixed to the vehicle body side. The seatbelt buckle 5 side of the stay 6 protrudes from the service hole cover 3 over a length that allows the cover 3 to open into the vehicle interior. Due to the simple configuration, when a tensile load is applied to the seat belt buckle 5, the load can be reliably received on the vehicle body stationary member side via the stay 6 and the support member 7. However, when opening the service hole 2, the service hole cover 3 can be freely opened without the stay 6 or the seat belt buckle 5 posing any obstruction.
