Abstract

PURPOSE:To improve the fitting property of a seat belt by supporting the upper portion of a webbing in the upright state via a flexible connecting member and a belt guide when an arm rest is prostrated forward to the using position in a seat having the arm rest storable in the storage recess of a seat back. CONSTITUTION:When an arm rest 11 is stored in a storage recess 12 for the seating of three persons, a flexible connecting member 14 is loosened, a belt guide 10 is dropped by its tare weight and located at the lower position of a webbing 2, the upper portion of the webbing 2 is exposed, the unsupported upper portion is bent along the surface of a seat cushion 7a. The seat space can be secured under this condition although the fitting property of a seat belt is not good. When the arm rest 11 is prostrated forward for the seating of two persons, the flexible connecting member 14 is pulled, the belt guide 10 connected to it is slid upward and located at the upper position of the webbing 2, the upper portion of the webbing 2 is set to the upright state by the belt guide 10, and the fitting property of the seat belt is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seat belt buckle structure for an automobile.

[Prior art]

It is well known that conventional seat belt buckles include webbing type buckles and webbing self-supporting type buckles.

In the former case, as shown in FIG.
The webbing 2 is inserted between the rear end of the seat cushion 7a and the lower end of the seat back 7b of the seat 7.

On the other hand, in the latter case, as shown in FIG. They are fitted and inserted into a substantially vertically extending through hole 9 formed in the seat cushion 7a of the seat 7.

[Problem to be solved by the invention]

However, the former webbing type requires the occupant to use both hands to fasten the seat belt.
Seat belts are not easy to wear. - On the other hand, the latter self-supporting webbing type allows the seatbelt to be fastened with one hand, but there is a problem in that it is difficult to secure seating space when seating three people.

The present invention has been made by focusing on such conventional problems, and provides a seat belt buckle that improves the ease of wearing the seat belt when seating two people, and also ensures sufficient seating space even when seating three people. The purpose is to provide structure.

[Means to solve the problem]

In order to achieve this object, the present invention provides an armrest that can be stored in a storage recess provided in the Jido Park, is pivotably supported in the storage recess, and has an armrest function when folded forward. In the seat, a buckle is attached to the tip and the base end is fixed to the floor or the sliding device, and the belt guide is slidably fitted to the webbing that is inserted into a vertically extending through hole bored in the seat cushion of the seat. On the other hand, the belt guide and the armrest are interlocked via a flexible connecting member, and when the armrest is stored in the storage recess, the belt guide is positioned below the through hole, and When the armrest is tilted forward,
The belt guide is arranged above the through hole so that the webbing is erected.

[For production]

In the case of a three-seater, if the armrest is stored in the storage recess, the visibility connecting member will loosen and the belt guide will fall under its own weight and be fixed at a position below the webbing, exposing the upper part of the webbing. flexes and conforms to the surface of the seat cushion, ensuring seating space.

In addition, in the case of a two-seater, if you move the armrest forward,
When the flexible connecting member is pulled, the belt guide connected to it slides upward along the webbing and is placed above the webbing, and the upper part of the webbing is held upright by the belt guide supported in the through hole. This makes it easier to wear the seat belt.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings, in which the same parts and parts as those of the conventional example are given the same reference numerals.

In FIG. 1, the base end of the webbing 2 with the buckle 1 attached to the tip is attached to the floor 4 with a bolt 5 via an anchor 3.
- fixed by a nut 6;

A resin cylindrical belt guide 10 having a length of about half of the webbing 2 is slidably fitted to the webbing 2,
It is inserted into a substantially vertically extending through hole 9 formed in the seat cushion 7a of the seat 7.

The seat 7 is a seat with an armrest, and has an armrest 11 on the seat back 7b. This armrest 11 can be stored in a storage recess 12 formed in the seat back 7b, and a hinge 13 is attached to the inner wall of this storage recess 12.
It is rotatably supported via a shaft, and functions as an armrest when folded forward as shown in Fig. 2.

A flexible connecting member 14 such as a wire or a band is connected between the lower end of the armless) 11 and the lower end of the belt guide lO.
The belt guide 10 and the armrest 11 are connected to each other so that the belt guide 10 interlocks with the armrest 11.

The length of the flexible connecting member 14 is such that when the armrest 11 is stored in the storage recess 12 (see FIG. 1), the belt guide 10 is positioned below the webbing 2, and the armrest 11 is When moved forward (second
(see figure), the belt guide IO is set to be placed above the webbing 2.

In the figure, 15 is a seat frame, and 16 is an insertion hole for the flexible connecting member 14 formed in the seat cushion 7a.

Next, the effect will be explained.

In the case of seating three people, as shown in FIG. 1, if the armrest 11 is stored in the storage recess 2, the flexible connecting member 1
4 relaxes and the belt guide 10 falls under its own weight and is placed below the webbing 2, exposing the upper part of the webbing 2, and the upper part, which is no longer supported, bends and follows the surface of the seat cushion 7a. . In this way, the seat belt is of the conventional webbing type, and although it is difficult to attach the seat belt, it can secure seating space.

On the other hand, in the case of a two-seater, move the armrest 11 by arrow a
The armrest 11 rotates in the direction shown in FIG.
When the flexible connecting member 14 is tilted forward, the flexible connecting member 14 is pulled, and the belt guide 10 connected thereto slides upward along the webbing 2 and is placed above the webbing 2. Thus, the upper portion of the webbing 2 is kept upright by the belt guide 10. In this way, it becomes a conventional self-supporting type, and can be worn with one hand, which means that the seatbelt can be easily worn.

The webbing 2 may not only be attached to the floor 4 but also supported by a seat slide device.

〔effect〕

As explained above, according to the present invention, an armrest is provided which can be stored in a storage recess provided in a seat back, is rotatably supported by the storage recess, and functions as an armrest when folded forward. In a seat with an armrest, a buckle is attached to the tip, the base end is fixed to the floor or a sliding device, and the belt guide is slidably inserted into the webbing that is inserted into a vertically extending through hole drilled in the seat cushion of the seat. While being fitted, the belt guide and the armrest are interlocked via a flexible connecting member, and when the armrest is stored in the storage recess, the belt guide is positioned below the through hole. and when the armrest is folded forward, the belt guide is positioned above the through hole and the webbing is erected;
Not only is the seatbelt easy to wear when seating two people, but also a sufficient seating space can be secured even when seating three people.
