Abstract

The invention discloses a combined protection device of an automobile seat safety air bag plug connector, which is characterized by comprising the following components in percentage by weight: the front end of the safety airbag is provided with the airbag supporting plate, so that the pressure of a driver and passengers on the airbag when the driver and the passengers squeeze and press the back is weakened, and poor stressed contact of the plug connector due to the action of external force on the seat is avoided; meanwhile, the air bag plug connector is surrounded by the plug connector protection bracket, so that the plug connector is located in an independent area, and the phenomenon that the air bag fault lamp gives an alarm due to poor stress contact of the plug connector caused by the action of external force on the seat is thoroughly avoided.

Description

Combined protection device of automobile seat safety air bag plug connector

Technical Field

The invention relates to the technical field of automobile seat airbags, in particular to a combined protection device of an automobile seat airbag plug connector.

Background

With the continuous development of the automobile industry, automobile safety is more and more concerned, and safety airbag equipment is generally applied to vehicles. However, as the rate of side impact accidents of vehicles in traffic accidents increases, side airbags are also used in a large number of vehicles, such as seat airbags, and even have become standard. The side air bag is located the foaming of seat side, is connected through the gasbag plug connector between air bag gas generator and pencil, and gas generator leans on plug connector locking structure itself with the gasbag plug connector, keeps the assembled state.

Chinese patent No. CN 209366089U discloses air bag plug connector protection structure, and the patent is that a steel plate structure is fixed on an air bag bracket by welding, and the size is large, not only the foaming space is affected, but also the weight is high

When a passenger uses the vehicle seat, the body of the passenger does not move in a non-directional manner and often collides with the part of the side airbag, so that the problem of poor contact between the gas generator and the plug connector is caused, the phenomenon that the side airbag is mistakenly exploded or cannot be ignited is easily caused, and certain potential safety hazard is brought to the passenger. Meanwhile, after-sale problems frequently occur, and in normal use of an after-sale vehicle, the phenomenon that an air bag fault lamp alarms occurs in an air bag side air bag of the automobile seat, and the fault is diagnosed to be too high or too low of resistance value of an air bag resistor, and the phenomenon generally caused by poor contact of a connector clip. The cause of poor contact is generally caused by two conditions:

1. when the seat is assembled, the wiring harness plug connector locking buckle is not locked or is not completely locked, and is separated after the vehicle is used for a period of time, so that poor contact of the plug connector is caused;

2. because the pencil arranges the trend improper, plug connector and pencil are wrapped up by the seat foaming, extrude the back repeatedly when driver and crew take, lead to plug connector and pencil to be extruded.

Disclosure of Invention

The invention discloses a combined protection device of an automobile seat airbag plug connector, aiming at the problems in the prior art, wherein an airbag supporting plate is arranged at the front end of an airbag, so that the force transmitted to the airbag plug connector is weakened, and meanwhile, the airbag plug connector is surrounded by a plug connector protection bracket, so that the airbag plug connector is not extruded.

The technical scheme adopted for realizing the invention is as follows: the utility model provides a combination protection device of car seat air bag plug connector which characterized by, it includes: gasbag backup pad 1, plug connector protective cradle 3 be the rectangle box body, plug connector

protective cradle

3 and 6 fixed connection of gasbag generator support, gasbag backup pad 1 can dismantle with air bag 4 and be connected.

Furthermore, the edges of the plug connector protection bracket 3 are all subjected to fillet flanging.

Further, the bending part of the plug protection bracket 3 has a local concave area.

Furthermore, a reinforcing rib is arranged at the bending part of the air bag supporting plate 1.

Further, the material of the airbag supporting plate 1 is a PP material.

Further, the thickness of the airbag supporting plate 1 is 2 mm.

The combined protection device of the automobile seat safety air bag plug connector has the beneficial effects that:

1. a combined protection device of an automobile seat safety air bag plug connector is characterized in that an air bag supporting plate is arranged at the front end of an air bag, so that the pressure of a driver and a passenger on the air bag when the driver and the passenger squeeze a backrest can be sufficiently weakened, the force transmitted to the air bag plug connector is further weakened, the situation that the plug connector is in poor contact due to the fact that external force acts on the seat and the force is applied to the plug connector is avoided, and the guide effect of air bag unfolding can be achieved; 2. the utility model provides a combination protection device of car seat air bag plug connector, plug connector protective cradle centers on the gasbag plug connector, makes the plug connector be located an independent little region to thoroughly avoid leading to the plug connector atress contact failure because external force acts on the seat, so that the phenomenon of gasbag trouble lamp warning.

Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-5 and the specific embodiments described herein, which are provided for illustration only and are not intended to limit the present invention.

As shown in figure 1, gasbag backup pad 1 is located gasbag 4 and the foaming of seat flank front end, between the 5 sides of seat skeleton, it is fixed with seat skeleton 5 through gasbag 4, gasbag 4 transversely fixes on

seat skeleton

5, 7 interfaces of air bag generator are downward, gasbag plug connector 2 is located gasbag 4 below, and insert 7 poor interfaces of inserting of gasbag generator, gasbag generator support 6 can dismantle with gasbag backup pad 1 and be connected, be provided with the protecting support 3 of plug connector in the 2 outsides of gasbag plug connector, plug

connector protecting support

3 and 6 formula as an organic whole of gasbag generator support, can constitute the trilateral protection to gasbag plug connector 2 with seat skeleton 5, thereby avoid the extrusion of seat foaming to the plug connector.

The gasbag backup pad adopts the PP material, and thickness is 2mm, presses close to 5 a side surfaces of seat skeleton and is the plane, and inside has strengthening rib structure 101, as shown in attached figure 2, presses close to the part of gasbag front end unanimously with the flank profile, guarantees to closely laminate with the foaming.

The 3 edges of the plug connector protection bracket are all rounded and flanged, so that on one hand, long-time foaming is avoided from being cut by friction with foaming contact, and on the other hand, the air bag is prevented from being scratched by sharp edges or burrs when the air bag is unfolded.

The bending part of the plug connector protection bracket 3 is provided with a local sunken area, so that the strength of the bracket is ensured, and the deformation under external force is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
