JP2519652Y2 - Mounting structure for movable shoulder anchors for seat belts - Google Patents

Description

TECHNICAL FIELD The present invention relates to a mounting structure for mounting a shoulder anchor of, for example, a three-point type seat belt on a center pillar or the like so as to be vertically adjustable.

2. Description of the Related Art A three-point seat belt that restrains the waist and upper torso at the same time is used in the front seats of most automobiles because it has excellent occupant protection performance in the event of a collision. The shoulder anchor that supports the upper end of the shoulder belt in the three-point seat belt, in a normal passenger car, assumes the average body shape of the occupant,
It is generally fixedly attached to the optimum position of the center pillar.

However, if the shoulder anchor is fixed in this way, when the occupant has a low sitting height, a part of the shoulder belt may be hung on the neck, and conversely, when the sitting height is high, There are problems such as being hung on the arm and hindering driving and lowering the protection performance.

As a solution to these problems, recently, a movable shoulder anchor device has been installed in which the shoulder anchor is attached to the center pillar so that the vertical position can be adjusted, and the shoulder belt ensures an optimum position that matches the sitting height of the occupant. Proposed.

FIG. 3 is a horizontal cross-sectional plan view of an anchor portion showing a conventional shoulder anchor mounting structure, with the lower side in the figure being the passenger compartment side. In the figure, 01 is a center pillar that is erected vertically, and has a generally U-shaped pillar outer 02 whose outer surface is bent in a chevron shape and a pillar inner 03 which is outwardly U-shaped.
It is configured by fixing.

A guide rail 04 having a central portion bulged outward is fixed to a proper position on the inner surface of the pillar inner 03 so as to face the vertical direction. A substantially C-shaped slider 06 having a nut 05 fixed to the center of the guide rail 04 is slidable in the vertical direction and is locked at an arbitrary position of the guide rail 04 by a locking means (not shown). It is fitted so that it can.

Anchor bolts 08 that support the belt support 07 are screwed onto the nut 05.

Reference numeral 09 is a trim material that covers the slider 06, the guide rail 04, the pillar inner 03, and the like, and a slit-shaped cutout hole 010 that faces the up-down direction is formed in the insertion portion of the anchor bolt 08.
The notch hole 010 is closed by moving the cover 011 fixed to the nut 05 between the trim material 09 and the slider 06 up and down together with the anchor bolt 08 and the slider 06.

Problems to be Solved by the Invention In the above-described conventional structure, the guide rail 04 is simply fixed to the inner surface of the pillar inner 03, and the slider 06 is fitted to this, so that the anchor portion protrudes toward the inside of the room, and it looks good. Not preferable.

In addition, it is necessary to increase the fitting allowance between the guide rail 04 and the slider 06 so that the guide rail 04 and the slider 06 do not easily come off during a collision or the like. May interfere with

The present invention was made in order to solve the above problems, and the purpose thereof is to make it possible to make the pillar portion thinner and to reduce the protrusion of the anchor portion to the indoor side, so that the appearance etc. It is to provide a mounting structure of a shoulder anchor that can improve the.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention forms a pillar outer that is erected vertically and has a generally U-shape in plan view, and a pillar inner that is mounted inside the pillar outer. In addition, a guide member having a guide groove of a required length that is oriented in the vertical direction at a proper position on the inner side surface, a slider that is vertically slidably mounted in the guide member, and the guide groove is inserted. It is characterized in that it is provided with a belt support for supporting the shoulder belt of the seat belt, and with an anchor bolt that is vertically adjustable and is coupled to the slider.

By mounting the guide member that guides the slider in the pillar outer and housing the entire slider in the guide member, it is possible to make the pillar thinner while maintaining a reliable fit between the guide member and the slider. Become. Further, the members protruding toward the vehicle interior side are only the anchor bolts and the belt supporting member, so that the protruding amount can be minimized.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a side roof rail and a side sill (both not shown) at the upper and lower ends, respectively.
The center pillar is fixed to the outer pillar (upper side in FIG. 2) of the vehicle body and is bent in a chevron shape to form a generally U-shaped pillar outer 2 and a C-shaped cross-section mounted inside the pillar outer 2. It is composed of a guide member 3. The guide member 3 also serves as a pillar inner forming the center pillar 1.

Reference numeral 4 denotes an anchor bolt inserted from the inside of the vehicle into an appropriate position of a guide groove 3a formed in the inner surface of the guide member 3 and extending vertically after the belt support 5 for supporting the shoulder belt is loosely inserted. A rectangular plate-shaped slider 6 fitted in the guide member 3 so as to be vertically slidable is screwed to the portion.

The slider 6 can slide up and down within a predetermined section that comes into contact with stoppers (not shown) provided at two upper and lower positions in the guide member 3, and has locking means at appropriate places not shown. It can be locked at any position by operating.

Reference numeral 7 is a trim member that covers the inner surfaces of the pillar outer 2 and the guide member 3, and has a notch hole 7a formed in the vertical direction so that the anchor bolt 4 that passes through the trim member can be moved up and down without hindrance. Reference numeral 8 denotes a cover which constantly closes the cutout hole 7a, and by inserting and fixing the anchor bolt 4, the guide member 3 and the trim member 7 can be slid up and down together with the anchor bolt 4. ing.

Reference numerals 9 and 10 denote front and rear side doors provided on the outer side of the pillar outer 2 so that they can come into contact with the outer side surface of the pillar outer 2 via a weather strip 11.

The guide member 3 may have a closed cross-sectional shape, and the guide groove 3a may be formed by vertically notching only the insertion portion of the anchor bolt 4 in an adjustable range.

Advantageous Effects of Invention According to the present invention, the guide member for guiding the slider is fitted and fixed in the outer pillar of the pillar, and the slider is fitted in the guide member. In any case, it is possible to reliably maintain the fitting between the guide member and the slider and to make the pillar thin without increasing the size. Further, since the guide member also serves as the pillar inner, there is an advantage that the number of constituent parts of the center pillar is small and the structure can be simplified. Further, since the conventional pillar inner does not exist, it is possible to minimize the protrusion amount of the shoulder anchor portion such as the anchor bolt toward the vehicle interior side. As a result, the appearance is improved and the visibility is good.
