Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a rail attachment device for a passive seat belt in a motorized side rail movable anchor type passive seat belt system for a vehicle.

[Conventional technology]

Conventionally, as this type of passive seat belt rail attachment device, one shown in FIG. 4 has been known. In the figure, reference numeral 1 is an inner panel serving as a mounting surface or its auxiliary member, 2 is a bracket for attaching the rail, 3 is a bracket that cooperates with bracket 2 to sandwich the rail, 4 is a guide rail,
5 shows a slider, 6 shows a shoulder belt runner, and 7 shows a tightening bolt. In the rail mounting device with such a configuration, when a lateral force F is applied to the belt runner 6, the rotational moment generated in the guide rail 4 via the slider 5 due to this force F is A force is applied to push the brackets outward at points a and b, and as shown in FIG. It was difficult to hold it securely. For this reason, a device in which the bracket is integrated has been proposed, as shown in, for example, Japanese Utility Model Application Publication No. 57-109049. In FIG. 5 showing this conventional example, numerals 1, 4 to 7 are the same as those shown in FIG. 4, and 2' is an integrated bracket made of spring steel. Since the bracket 2' is integrally formed with a spring material, its opening distance l will change even if a lateral force F is applied to the belt runner 6. In addition, the bracket 2' receives the rotational moment while firmly holding the guide rail 4, and as shown in FIG. can be held.

[Problem that the invention attempts to solve]

In the conventional guide rail mounting device as described above, in order to securely hold the guide rail 4, spring steel must be used for the bracket 2', resulting in high cost. Another problem is that the strength and rigidity of the bracket 2' must be determined by selecting the material and thickness within a range that allows the installation work of the guide rail 4, and it is not always possible to obtain a sufficient holding function. It was hot. In addition, in order to improve the holding performance, it has been proposed that the bracket and the guide rail be assembled via a separate part such as a lip.
In this method, the assembling operation must be carried out by climbing over the lip, resulting in poor workability and a problem of lowering the rigidity of the bracket body. This idea was made to solve the problems mentioned above, and it eliminates the constraints on the strength and rigidity of the bracket, greatly increasing its rigidity, and also reduces the installation work without increasing costs. It is an object of the present invention to provide a rail attachment device for a passive seat belt that can improve performance.

[Means to solve the problem]

In order to achieve the above object, this invention is an electric side rail movable anchor type passive seat belt system, in which the guide rail attachment part is composed of two brackets, and one of the brackets is attached to the guide rail. One bracket is formed in a shape that holds the upper inner surface and the lower outer surface, and the other is formed in a shape that holds the upper outer surface and lower inner surface of the guide rail, and the upper ends of both the brackets are fastened together to form a mounting material. It is characterized in that it is constructed so that both brackets are intertwined and the guide rail is sandwiched between the two brackets when the guide rail is attached.

[Effect]

In the device based on this invention, two brackets are combined so that they are intertwined with each other, the guide rail is supported within the rail holding part formed by this combination, and both brackets are connected to tightening bolts. Then, attach it to the mounting surface and tighten it.
One bracket strongly contacts the upper inner surface and lower outer surface of the guide rail, and the other bracket strongly contacts the upper outer surface and lower inner surface of the guide rail, sandwiching the guide rail to provide strong support. .

There is an insertion hole 2j at the boundary between the mounting surface 2a and the horizontal holding surface 2b, and a downwardly bent vertical holding portion 2f is protruded from the edge of the insertion hole 2j (horizontal holding surface 2b) to provide vertical holding. A trim attachment receiving portion 2g having a spring function is provided on the surface 2c. Reference numeral 3 designates a bracket, which has a bifurcated portal shape at the bottom, a bracket main body surface 3a having a bent portion 3b at each lower end, and a horizontally bent tip bent downward from the bracket main body surface 3a. It is formed of a horizontal holding surface 3c having a bent portion 3d, and an oblong mounting hole 3e is bored in the upper part of the bracket main body surface 3a. Reference numerals 4 to 7 are the same as those shown in FIGS. 4 and 5, and 4 is a guide rail, 5 is a slider, 6 is a belt runner, and 7 is a mounting bolt, respectively. Next, the assembly and its operation will be explained. First, insert the bracket 3 into the bracket 2 so that the bracket main body surface 3a is on the mounting surface 2a, the horizontal holding surface 3c is on the horizontal holding surface 2b,
The bent parts 3d are intertwined with each other so as to fit into the opening formed by cutting and raising the trim attachment receiving part 2g, and the guide rail 4 is inserted therein.
Overlap the mounting holes 2e and 3e of both brackets 2 and 3, pass the mounting bolt 7 through these, and attach it to the mounting material 1.

f holds the upper inner surface of the guide rail 4, its vertical holding surface 2c holds the lower outer surface of the guide rail 4, and its lower end bent portion 2d holds the lower end of the guide rail 4, respectively. On the other hand, the bracket 3 has a main body surface 3a.
The lower inner surface and lower end of the guide rail 4 are held by the bent portion 3b and the upper outer surface of the guide rail 4 is held by the bent portion 3d of the horizontal holding surface 3c. Hold 4 firmly. In the rail mounting device of this invention, when a lateral force F is applied to the belt runner 6 as shown in FIG. 2, the rotation moment of the guide rail 4 is a force Fa,
In the conventional model, both forces were received by the same member, resulting in large deformation, but the force Fa at point a is applied to the two brackets 2 and 2.
3, and the force Fb at point b is received by bracket 2, and since both brackets 2 and 3 have no restrictions on strength or rigidity as seen in conventional integral structures, the rigidity of each can be selected arbitrarily. This makes it possible to firmly hold the guide rail 4 without deforming it. Another embodiment is shown in FIG. In the figure, numeral 2 is a bracket, numerals 2a to 2g are the same as those shown in FIG.
