Description

[Detailed Description of the Invention] This invention relates to a guide rail device for an automatically installed safety belt that moves the automatically installed safety belt in the longitudinal direction of a vehicle in response to the entry and exit of an occupant into a vehicle compartment.

Conventionally, guide rails for automatically installed safety belts, which are disposed along vehicle body strength members such as roof side rails facing into the vehicle interior, have been fixed to the vehicle body strength members using retainers. , strips 3,3 as shown in FIG.
To fix the guide rail to the vehicle body strength member, a retainer different from the guide rail fixing retainer was used. In this way, the conventional retainer has two separate parts, one for fixing the guide rail 1 to the vehicle body strength member 2 and the other for fixing the strip 3 to the guide rail 1. The number increases, which necessarily increases the cost of the guide rail device.

In this regard, future performance improvements were desired.

The purpose of this invention is to reduce the number of parts and further improve the above-mentioned conventional performance by holding and supporting the guide rail and the strip with one type of retainer.

In order to achieve this purpose, the configuration of the guide rail device of the automatically installed safety belt of this invention is as follows:
A guide rail 1 made of resin or the like and having a U-shaped cross section is connected to retainers 4, 4a through a strip 3.
The safety belt is gripped and supported by the vehicle body strength member 2 and is disposed along the longitudinal direction of the vehicle on the vehicle body strength member 2 with its longitudinal direction facing the interior of the vehicle, and automatically attached safety belts are attached in the longitudinal direction of the vehicle in response to the entry and exit of passengers into the vehicle interior. It is designed to be moved.

The opening edge 12 of the guide rail 1, which has a U-shaped cross section, is arranged to face downward in the vertical direction of the vehicle. are interlocked in a concave and convex manner.

Then, the guide rail 1 is inserted through the strip 3.
A claw piece 400 is provided at the opening edge of the retainer 4, 4a that grips and supports the retainer.
0 is formed so as to hug the opening edge 12 of the guide rail 1.

According to the guide rail device for an automatically installed safety belt according to this invention, (i) a strip is engaged with the side part of the outer skin of the guide rail, which is formed into a U-shaped cross section, and the guide rail is inserted through the strip by a retainer; Since the rail is gripped and supported, and the opening edge of the guide rail is held by the claws provided on the retainer, the following effects (a) and (b) are achieved.

(a) The ease of assembling the coid rail and strip is improved, and the number of assembly steps can be reduced.

(b) The number of retainer parts can be reduced and an inexpensive guide rail device can be provided.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Figures 1 to 3b show an embodiment of this invention, and as shown in Figures 1 and 2, it can also be made of resin, etc. (other than resin, for example, aluminum die-casting, etc.). ), the guide rail 1 is shaped like a U-shape in cross section, and is gripped and supported by a retainer 4 via a strip 3, and its longitudinal direction is connected to a vehicle body strength member 2 (such as a roof side rail) facing into the passenger compartment. The safety belt hanger S attached to the safety belt is inserted into the groove 11 of the guide rail 1 to allow passengers to get on and off the vehicle. In response to this, the automatically installed safety belt is moved in the longitudinal direction of the vehicle.

Further, the opening edge 12 of the guide rail 1 having a U-shaped cross section is arranged to face downward in the vertical direction of the vehicle, and a recess 100 is provided in the side part 10 of the outer skin of the guide rail 1. This recess 100 has one side 3 of the strip 3 formed of an elastic material such as rubber.
The protrusions 300 provided at 0 are engaged with each other.

Incidentally, a fin portion 31 is formed on the other side of the strip 3 away from the concave portion 300. The retainer 4 made of spring material is attached to the strip 3.
to grasp and support the guide rail 1 through the
The retainer 4 has a U-shaped cross section, and claw pieces 400, 400 are provided at the opening portion 40 of the retainer 4. , 12.

As can be seen from FIGS. 3a and 3b, the retainer 4 also includes a top surface 41, a slope 42,
42, a notch 43 is provided, and the mounting seat 44 is cut and raised from this notch 43, and a long hole 440 provided in the mounting seat 44 is connected to the hole 2 drilled in the vehicle body strength member 2 such as the roof side rail.
0, the retainer 4 is fixed to the vehicle body strength member 2 with bolts B.

Note that W is a washer and N is a nut welded to the vehicle body strength member 2. 4 and 5, the strip 3 and the guide rail 1 are fixed by the retainer 4a, excluding the notch 43 and mounting seat 44 provided in the retainer 4 shown in FIGS. 3a and 3b. The rest of the configuration is the same as that shown in FIG. 2, so the explanation will be omitted.
