[0009] An airbag mounting bracket includes an integrally formed tubular body and an arc-shaped groove body; wherein:

[0010] The tubular body and the arc-shaped groove body are coaxial;

[0011] A mounting plate is disposed at the free end of the arc-shaped groove body, and a mounting hole is formed on the mounting plate.

[0012] The mounting bracket of the airbag is in the shape of an elongated strip as a whole, and its surface is an arc-shaped structure, which is convenient for fixing the generator during assembly; one end of the mounting bracket of the airbag is a tubular body, which can prevent the exhaust gas of the generator from damaging the bag; the other end of the mounting bracket of the airbag is a mounting plate, and the mounting plate is provided with mounting holes, which can reduce the layout space of the body sheet metal.

[0013] Preferably, the mounting hole is a round hole or a long hole.

[0014] Preferably, two claws are symmetrically arranged on both sides of the arc-shaped groove body. The claws are symmetrically distributed on both sides of the mounting bracket of the airbag, which can reduce the possibility of twisting or stretching deformation of the mounting bracket of the airbag.

[0015] Preferably, one end of each of the clamping claws is provided with a clamping slot, and a mounting slot matching the clamping slot is provided on the body sheet metal, and when the mounting bracket of the airbag is mounted on the body sheet metal, the clamping claw plays a role of pre-fixing the installation.

[0016] Preferably, notches are provided on the arc-shaped groove body at positions corresponding to both ends of the clamping claw, so as to facilitate the bending process of the clamping claw.

[0017] Preferably, the positions at both ends of the claws on the arc-shaped groove body are reserved for the installation of the clamp. After the mounting bracket of the airbag and the generator are installed and put into the bag, the clamp can be installed at the position of the limiting section to play a limiting role.

[0018] Preferably, a transition arc surface is provided between the arc-shaped groove body and the mounting plate.

[0019] Preferably, a reinforcing rib is provided on the arc-shaped groove body between the two clamping claws to increase the strength of the arc-shaped groove body.

[0020] Preferably, a boss is provided on the arc-shaped groove body between the two claws, which plays an interference fit role with the body sheet metal, and can eliminate abnormal noise and looseness caused by the collision between the airbag mounting bracket and the body sheet metal.

[0021] Preferably, the tubular body is provided with an opening extending in the axial direction.

[0022] The beneficial effects of the present invention are as follows: the claws of the airbag mounting bracket are symmetrically distributed, and the mounting point of the airbag mounting bracket and the vehicle body sheet metal is located at the end of the bracket (that is, the mounting hole of the airbag mounting bracket is arranged at the end of the bracket), which reduces the layout space of the vehicle body sheet metal and improves the versatility of parts; a reinforcing rib design is added to the airbag mounting bracket to increase the strength of the bracket; and an interference structure design is added (one or more bosses are provided on the arc-shaped groove body) to eliminate abnormal noise.

[0032] The structure of the present invention is explained in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 7 As shown, a first embodiment of the present invention provides an airbag mounting bracket, which is in an elongated shape as a whole, and includes an integrally formed tubular body 1, an arc-shaped groove body 2, a transition arc surface 4 and a mounting plate 3; wherein,

[0034] The tubular body 1 and the arc-shaped groove body 2 are coaxial; the tubular body 1 is provided with an opening 11 extending in the axial direction, and the mounting plate 3 is provided with a mounting hole 31, which is a round hole or a long hole. The mounting plate 3 can be a flat plate or a boss plate.

[0035] The first embodiment of the present invention provides an airbag mounting bracket, wherein two claws 21 are symmetrically provided on both sides of the arc-shaped groove body 2. A slot 211 is provided at one end of each claw 21, and the slot 211 can be forward or backward, but the opening direction of the slots 211 of the two claws 21 must be the same. The body sheet metal 5 is provided with an installation groove that matches the slot 211. When the airbag mounting bracket is installed on the body sheet metal 5, the claw 21 is clamped in the installation groove of the body sheet metal 5 to play a role in pre-fixing the installation. Then the bolt 6 is installed in the installation hole 31 of the mounting plate 3 to lock and fix the airbag mounting bracket to the body sheet metal 5.

[0036] In the first embodiment of the present invention, a mounting bracket for an airbag is provided, wherein the arc-shaped groove body 2 is provided with notches 22 at positions corresponding to both ends of the clamping claw 21. This facilitates the bending process of the clamping claw 21. The positions at both ends of the clamping claw 21 on the arc-shaped groove body 2 are reserved with limiting sections 23 for installing the clamp 7. After the mounting bracket for the airbag and the generator 8 are installed and put into the bag, the clamp 7 can be installed at the position of the limiting section 23 to play a limiting role.

[0037] In the first embodiment of the present invention, a mounting bracket for an airbag is provided, wherein a reinforcing rib 24 is provided on the arcuate groove body 2 between the two claws 21, which serves to increase the strength of the arcuate groove body 2. A boss 25 is provided on the arcuate groove body 2 between the two claws 21, which serves to achieve an interference fit with the body sheet metal 5, thereby eliminating abnormal noise and looseness caused by the collision between the mounting bracket for the airbag and the body sheet metal 5.

[0038] like Figure 8 As shown, in a second embodiment of the present invention, an airbag mounting bracket is provided, wherein the opening direction of the slots 211 on the two claws 21 is opposite to the opening direction of the slots 211 on the claws 21 of the airbag mounting bracket provided in the first embodiment of the present invention.

[0039] The first and second embodiments of the present invention provide an airbag mounting bracket, the material of which is not limited and can be a metal part, an injection molded part or other molded parts.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and simple improvements made to the essential contents of the present invention should be included in the protection scope of the present invention.
