Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of Invention] (Industrial field of application) The present invention relates to an adjustable shoulder anchor device in which a vehicle body is attached to a pillar and an anchor point of a seat bell can be adjusted in a vertical direction. It relates to a garnish structure that obtains an increase in its stroke.

(Prior Art) By law, automobiles, which are vehicles, must be equipped with the most inexpensive and effective seat belts as occupant protection devices, and the recent revision of the law requires occupants to wear seat belts. became.

The types of seat belts are roughly classified into two-point seat belts, diagonal seat belts, three-point seat belts, and full harness seat belts. The above-mentioned two-point type seat belt is also called a waist belt or the like and is a basic one applied to the widest range. However, it cannot be said that protection in a state at the time of collision is sufficient, and its use alone is not ideal. Currently used mainly for rear seats. The diagonal seat belt is also called a shoulder belt or a shoulder belt. This has the problem that the lower half of the body slips forward in the event of a collision and is not currently used. The full-harness type seat belt has excellent occupant protection performance, but has a problem in practical use, and is currently limited to only special uses.

The above-mentioned three-point type seat belt is excellent in occupant protection performance and highly practical, and is currently most frequently used. This is a combination of the above-mentioned two-point belt and the shoulder belt, and a method in which the shoulder belt and the waist belt are continuously webbed is widely used for easy use.

By the way, the required specifications of this type of three-point seat belt are specified in detail, and one of them is a mounting portion (anchorage). That is, the placement of the anchorage for the occupant has a great influence on the occupant protection performance and comfort when wearing the belt. If the position of this anchorage is not good, the so-called submarine phenomenon may occur in which the lower half of the body crawls forward in the event of a collision. Also, especially if the anchor point is not positioned properly, the occupant may hang his / her neck on the shoulder belt,
The upper body may fall out.

However, the heights of the occupants are various, and as long as the anchor point is constant, some occupants may encounter the above accident. Therefore, recently, adjustable shoulder anchor devices have been adopted. This is to attach an anchor point of the anchorage to a pillar of a vehicle body so as to be displaceable in the vertical direction so that an occupant can select and adjust an optimum position.

Specifically, for example, a center pillar of a vehicle body is provided with a rail body having a plurality of engaging holes at predetermined intervals in the vertical direction, and the rail body is slidably engaged with the rail body in the vertical direction. A knob that can be operated from the room side and an anchor point for the shoulder belt are provided. Since the tip of the knob engages with and disengages from the engagement hole of the rail body, when adjusting, grasp the knob and pull out this end from the engagement hole, and move the slider upward or downward as it is, and the anchor point is optimal. Once in position, the end is engaged with another engagement hole by releasing the knob to retain the slider position. That is, the position of the anchor point is optimal so that the shoulder belt hits the approximate center of the clavicle of the occupant.

Note that such an adjustable shoulder anchor device is covered with pillar trims so that it cannot be seen by passengers in the passenger compartment. Further, since the knob naturally projects from the pillar trim toward the vehicle compartment, it is necessary to open a long hole in the pillar trim in the vertical direction. On the other hand, when the length of the slider in the vertical direction is increased, the weight thereof becomes heavy, which makes it difficult to operate, and the upper end abuts on the roof rail or the lower end largely protrudes from the rail body. Therefore, although the vertical dimension of the slider is set as short as possible, the elongated hole of the pillar trim cannot be closed by the slider, and the center pillar can be seen through the elongated hole as it is. Therefore, it is necessary to interpose a blocking plate called a garnish between the slider and the pillar trim to shield the adjustable shoulder anchor device from the elongated hole.

By the way, in a passenger car, for example, since the vehicle height is high and the pillars are long, a sufficient stroke can be taken. Therefore, the conventional garnish is only one. However, since the length of the pillar is small in a vehicle with a low vehicle height such as a so-called coupe type vehicle, even if the adjustable shoulder anchor device is adopted, the stroke length is only short. Since the adjustment range of the anchor point is extremely limited, it is not possible to reliably prevent the occurrence of the above problems.

(Problems to be Solved by the Invention) The present invention provides a sufficient stroke length of the anchor point and expands the application range even in the case of the vehicle having a low vehicle height as described above and the pillar length. It is an object of the present invention to provide a garnish structure of an adjustable shoulder anchor device that can achieve higher reliability and improved reliability.

[Constitution of device]

(Means for Solving Problems) That is, according to the present invention, a rail body having a plurality of engaging holes at predetermined intervals in the vertical direction is attached to a pillar of a vehicle body, and a slider is attached to the rail body in the vertical direction. It is slidably engaged with the slider, and knobs that can be operated from the passenger compartment side and anchor points of the shoulder belt are provided at predetermined intervals in the vertical direction, and the tip of the knob is engaged with and disengaged from the engagement hole of the rail body. By making it possible to adjust the vertical position of the anchor point, the inner garnish longer than the slider that displaces integrally with the slider is overlaid on the slider, and the outer garnish can be slid on this inner garnish and the slider. To the
The outer garnish has a guide elongated hole through which a knob and an anchor point are inserted, which is a garnish structure of an adjustable shoulder anchor device.

(Operation) According to such a configuration, when the inner garnish is slidably adjusted together with the slider by sliding the knob upward or downward, the upper and lower ends of the guide elongated hole come into contact with the knob or the anchor point and together with the outer garnish. Further, it can be displaced upward or downward, and in the end, the anchor point position can be adjusted with a double stroke.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, reference numeral 1 is a pillar trim of a center pillar, and an upper end portion of the pillar trim is connected to a roof trim 2. An elongated hole 3 which is long in the vertical direction is provided in the middle of the pillar trim 1, and an adjustable shoulder anchor device A to be described later is provided.
Protrudes. That is, 5 is a knob that can be adjusted from the passenger compartment side, and 6 is a hook that hooks a webbing 7 that forms a shoulder belt. That is, the hook 6 forms an anchor point 8 of the shoulder belt.

The adjustable shoulder anchor device A will be further described below. It is as shown in FIGS. 2 and 3, and 10 is a rail body, which is a center pillar P of the vehicle body and has bolts at its upper and lower ends, It is attached by fixing tools 11, 11 made of nuts. A substantially central portion is bent in a U-shaped cross section, and a plurality of engaging holes 12 ... Are bored at a predetermined interval in the vertical direction. Both ends of the rail body 10 are integrally bent in the left-right direction, and the slider 13 is slidably engaged there. A support rod 15 is provided on the upper portion of the slider 13 so as to fit the knob 5 forward and backward, and a protrusion 16 is provided on the lower portion for supporting the anchor point 8 of the shoulder belt. The inner garnish 17 is superposed on the front surface side of the slider 13. The inner garnish 17 has a vertical dimension longer than that of the slider 13, is provided with a through hole 18 that fits with the support rod 15, and is provided with an anchor attachment portion 19 that engages with the protrusion 16. The end of the knob 5 can be inserted into and removed from the engaging hole 12 through the support rod 15. A spring mechanism is built into the inside, and when the occupant pulls the knob 5 from the passenger compartment side against this elastic force, this end part comes out of the fitting hole 12, and the slider 13 moves along the rail body 10. You can slide it up and down. Of course, if the knob 5 is released, the spring mechanism returns to the original state. On the other hand, the outer garnish 20 slidably engages the inner garnish 17 and the slider 13. That is, the inner garnish 17 and the rail portions 21 and 21 slidably engaged with the slider 13 are integrally provided on both sides of the outer garnish 20. A guide elongated hole 22 is provided on the surface side of the outer garnish 20 along the vertical direction, and the knob 5 and the anchor point 8 project. At the upper end of the elongated guide hole 22, the slider 1 is attached.
When the inner garnish 17 is slid together with the knob 3, the knob 5 comes into contact with the anchor point 8 at the lower end. If the slide is further biased in that direction, the slider 1
The outer garnish 20 together with the inner garnish 17 and the inner garnish 17 are moved in that direction. Eventually, these movements are restricted by the upper and lower ends of the elongated hole 3 provided in the pillar trim 1.

A clip support 23, which is bent into a substantially U-shape, is fixed to the upper end of the rail body 10 by a fixture 11 together. Spring clips 24, 24 are elastically attached to both ends of the clip support 23, and the pillar trim 1 is fitted from the vehicle compartment side as shown in FIG. That is, as described below, the inner garnish 17
Also, since the outer garnish 20 moves particularly upward, the pillar trim 1 cannot be attached to the pillar P in a vehicle with a low vehicle height. Therefore, the spring clips 24, 24 are attached to the upper end of the rail body 10 via the clip support 23, and the upper end of the pillar trim 1 can be easily attached to the upper end without any trouble.

Then, the occupant pulls the knob 5 and further urges it to slide upward or downward, whereby the anchor point 8
Can be set to the optimum position. As an actual operation, the inner garnish 17 slides together with the slider 13 by pulling the knob 5 and pulling out this end from the engaging hole 12 that has been engaged until then, and biasing it upward or downward. When the knob 5 or the anchor point 8 comes into contact with the upper end portion or the lower end portion of the elongated guide hole 22 provided in the outer garnish 20, the stroke is about half the maximum stroke. When the knob 5 is further urged to slide upward or downward, the support rod 15 that supports the knob 5 contacts the upper end of the guide elongated hole 22, or the anchor point 8 is formed at the lower end of the guide elongated hole 22. The outer garnish 20 slides with the hook 6 still in contact. Therefore, if the garnish has a double structure, the stroke for adjusting the position of the anchor point 8 can be lengthened even in an automobile having a low vehicle height and no pillar length.

[Effect of device]

As described above, according to the present invention, even in a vehicle having a low vehicle height and no pillar length, the double structure of the garnish makes it possible to extend the stroke for adjusting the position of the anchor point, which is convenient for use. Also, the effect of improving reliability can be obtained.
