        In general, a vehicle is provided with various types of passenger protection devices for the safety of passengers in case of emergency, and safety belts and airbag systems are known.

       Among such passenger protection devices, in particular, the airbag system is used in conjunction with the safety belt to prevent the body parts of the passenger's head, chest, knees, etc. hit the structure of the vehicle injuries injured in the collision of the vehicle. Among such airbag systems, an airbag system mainly employed in the front seat of a vehicle can be generally classified into a driver air bag and a passenger air bag.

1 is a view showing the structure of a passenger seat airbag of the vehicle, Figure 2 is a view showing a structure for mounting the housing and cowl cross bar.

As shown in FIG. 1, an inflator 8, a housing 1, an airbag cushion 2, and a reaction plate 6 are provided inside the instrument panel 5, and the airbag cushion 2 is provided. The driver's cab airbag door is distinguished by a tear seam 7 formed by laser scoring so that is easily deployed. When the gas is instantaneously filled in the airbag cushion 2 by the inflator 8, pressure is applied to one surface of the reaction plate 6, and the separation line 7 formed on the reaction plate 6 is provided. Tearing and the airbag cushion 2 is deployed.

Referring to FIG. 2, a mounting bracket 3 supports the housing 1 and connects the housing 1 and the cowl cross bar 3 with bolts d and nuts n.

However, in the mounting structure of the passenger seat airbag according to the prior art, the mounting bracket connecting the housing and the cowl crossbar does not absorb energy at all due to the impact, and therefore the head of the passenger due to the upper structure of the vehicle during a crash (HEAD-IMPACK) vehicle There is a problem that is damaged.

The present invention has been made to solve the above problems of the prior art, provided with a clip member to simplify the connection structure between the housing and the cowl cross bar to reduce the cost and impact energy during the collision of the vehicle to protect the head of the passenger The purpose is to prevent noise.

Mounting structure of the passenger seat airbag of the vehicle according to the present invention for solving the above problems, the housing is built in the instrument panel, the housing inside the airbag cushion and the inflator for deploying it to the gas pressure, the lower side of the housing Protruding members disposed at both ends include a protruding member having a through hole, a cowl cross bar disposed under the housing, and a clip member inserted into the through hole to connect the housing and the cowl cross bar. It features.

       The clip member may include a head having a circular hole for fastening with the cowl cross bar, a pivot shaft protruding outward to be inserted into the through hole of the protruding member, and the protruding member. It can be bent for fastening and consists of a body portion formed between the head and the pivot shaft portion.

       The clip member may be inserted into the through hole of the protruding member by using the elasticity of the body portion bent from the pivot shaft portion.

       In addition, a plurality of clip members are provided in the lower portion of the housing to couple with the protruding member of the housing.

       In addition, the head and the cowl cross bar of the clip member is characterized in that the bolt is fastened.

       In addition, the pivot shaft portion of the clip member which is inserted and coupled to the protruding member is characterized in that the rotation is installed.

       In addition, the clip member is characterized in that the steel material is good elasticity.

       In addition, the lower portion of the housing is characterized in that a plurality of the protruding members are arranged spaced apart from each other.

        The present invention provides a housing built into the instrument panel to prevent head damage and noise of a passenger during a collision of the vehicle, a cowl cross bar disposed under the housing, and an inside of the housing for deploying the airbag cushion and the gas pressure. In the configuration of a passenger seat airbag having an inflator, the protrusion member is disposed to protrude on one side of the lower part of the housing, and is inserted into and fastened to the through hole to connect the housing and the cowl cross bar at both ends of the protruding hole. By including the clip member, the clip member has the advantage of absorbing the impact energy during the collision of the vehicle to protect the head of the passenger and to prevent noise.

        Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a bottom view showing the housing of the passenger seat airbag according to the present invention, Figure 4a is a view showing a mounting structure of the housing and the clip member according to the present invention, Figure 4b is a clip member and cowl cross bar according to the present invention Figure is a diagram showing the mounting structure of the.

3 and 4, the mounting structure of the passenger seat airbag of the vehicle according to the present invention includes a housing 10 embedded in an instrument panel (not shown), and the inside of the housing 10 is an airbag cushion (not shown). And an inflator (not shown) for developing the gas pressure, a protruding member 15 protruding from one side of the lower portion of the housing 10, and having through holes 18 formed at both ends thereof, and the housing 10. The cowl cross bar 30 disposed below, and the clip member 20 is inserted into the through-hole 18 to connect the housing 10 and the cowl cross bar 30.

       Referring to FIG. 4, the clip member 20 is inserted into the through-hole 18 of the circular head portion 22 and the protruding member 15 that are bolted to the cowl crossbar 30. Rotating shaft portion 26 is formed to protrude outward and the body portion 24 formed between the head portion 22 and the rotating shaft portion 26 can be bent to fasten with the protruding member 15. It is composed.

       The clip member 20 is inserted into the through hole 18 of the protruding member 15 by using the elasticity of the body portion 24 bent from the pivot shaft portion 26.

       In addition, a plurality of clip members 20 are provided under the housing 10 in order to couple with the protruding members 15 of the housing 10.

       On the other hand, the head portion 22 and the cowl cross bar 30 of the clip member 20 is configured to be bolted (40).

       In addition, the pivot shaft portion 26 of the clip member 20 inserted into and coupled to the protruding member 15 is installed to be rotatable, and has good elasticity in steel, and is easily detachable to the housing 10.

      In addition, a plurality of the protruding members 15 arranged spaced apart from each other is formed below the housing 10.

Looking at the operation of the present invention configured as described above are as follows.

3 and 4, instead of deleting a mounting bracket (not shown) disposed under the housing 10 to connect the cowl cross bar 30 to the housing 10 by bolting, the housing 10 may be omitted. ) After forming the protruding member 15 by giving flesh to the lower itself, through holes 18 are formed at both ends of the protruding member 15. The clip member 20 is inserted into the through hole 18 to connect the cowl cross bar 30 disposed below the housing 10 to the housing 10. 20 forms a circular head 22 and bolts to the cowl crossbar 30, and the pivot shaft 26 of the protruding member 15 is inserted into the through hole 18 so as to be rotatable. The body part 24 is formed between the head part 22 and the pivot shaft part 26 to be fastened to the protrusion member 15.

       Referring to FIG. 4A, the clip member 20 is closed in the direction of the arrow by using the elasticity of the body portion 24 bent from the pivot shaft portion 26 to the through hole of the protruding member 15. 18) Insert and tighten.

      In addition, a plurality of clip members 20 are provided at the lower portion of the housing 10 to couple the protrusion members 15 of the housing 10, and with reference to FIG. The head 22 and the cowl cross bar 30 are fastened with bolts 40. As described above, when a head-impact impact is applied when the vehicle collides, it is simply fastened only by the elastic force of the clip member 20, and the binding force in the rotational direction is free, so that the deformation degree is small, and the shock is absorbed. This reduces passenger injuries.
