Abstract
A trim cover of a supplementary restraint system and installed on a car steering wheel comprises a trim cover body, wherein a square wide groove is formed in the middle position of the rear part of the trim cover body to form a reduction structure, two short reduction lines are arranged on two sides of the square wide groove, and a hammer-shaped groove is formed in the periphery of the trim cover body. According to the trim cover of the supplementary restraint system and installed on the car steering wheel, a traditional unfolding method of the supplementary restraint system is changed. A tearing line design is not adopted on the trim cover, the reduction structure of the square wide groove is formed in the rear part of the trim cover and as a flipping rotary shaft, material which the square wide groove is made of is pretty thin, and the square wide groove plays a role as the rotary shaft in a flipping process. Due to the adoption of the flipping structure, the periphery of the trim cover and a shell body of the supplementary restraint system are clamped through the hammer-shaped groove and a hammer-shaped head, the traditional unfolding method of the supplementary restraint system is changed, and the supplementary restraint system is easy to open. Meanwhile, due to the fact that the two short reduction lines arranged on the two sides of the wide groove are located behind the trim cover, surface quality of the trim cover is not affected even if injection molding shrinkage marks exist.
Description
Technical field
The present invention relates to a kind of decorative cover that is arranged on the safety air bag on vehicle steering.
Background technology
Existing air bag decorative cover is provided with the line of weakness structure, when airbag deployment, decorative cover is torn from the tear line position, material Thickness Ratio periphery material thin thickness due to the tear line position, the width of tear line is narrow, so the surface at the injection moulding process middle decorating cover easily produces the injection moulding shrink mark, affects the appearance quality of decorative cover.
Summary of the invention
Purpose of the present invention overcomes defects exactly, and a kind of decorative cover that is arranged on safety air bag is provided, and is easy to open, and improves the appearance quality of decorative cover A face.
Technical solution of the present invention is:
The decorative cover that this is arranged on the safety air bag on vehicle steering comprises the decorative cover body, is provided with square sipes at decorative cover rear body midway location and forms weakening structure, and square sipes both sides are provided with two short line of weakness, and decorative cover body periphery is provided with the capitate groove.
Described decorative cover body periphery also is provided with guide groove.
The invention has the beneficial effects as follows: the mode that has changed the conventional security airbag deployment, do not adopt the design of decorative cover tear line on decorative cover, be provided with the weakening structure of square sipes in the decorative cover back as renovating rotating shaft, the material thickness of square sipes is thinner, play the effect of a rotating shaft in the process of renovating, adopt flip structure, the decorative cover periphery clamps by capitate groove and capitate head with airbag housing, changed the mode of conventional security airbag deployment, be easy to open; Simultaneously, the both sides of sipes are provided with two short line of weakness, due in the back of decorative cover, even if the injection moulding shrink mark is arranged, also can not affect the surface quality of decorative cover.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, decorative cover body 5 rear portions are provided with square sipes 1 and form weakening structure, the left and right sides of square sipes 1 is provided with two short line of weakness 2L and 2R, square sipes 1 rear side is provided with backboard 3, decorative cover body 5 is connected as a single entity by square sipes 1 with backboard 3, the left and right sides of square sipes 1 is provided with two short line of weakness 2L and 2R, decorative cover body 5 peripheries are provided with decorative cover enclosure wall 4, backboard 3 and decorative cover enclosure wall 4 are perpendicular to decorative cover body 5 surfaces, backboard 3 is provided with square hole 3A, and decorative cover enclosure wall 4 is provided with a plurality of capitate groove 4A, guide groove 4B.
As shown in Figure 4, the material thickness D1 of square sipes 1 is thinner than the material thickness D2 of its periphery; As shown in Figure 5, short line of weakness 2R cross section triangularity, the base material thickness D3 of short line of weakness 2R is thin than the material thickness D4 of its periphery.The shape of short line of weakness 2L is identical with short line of weakness 2R.
As Fig. 6, shown in Figure 7, during installation, backboard 3 and the airbag housing 6 of this decorative cover are assembled together, and the square hole 3A on the backboard 3 of decorative cover and the boss 6A clamping on airbag housing 6.
As Fig. 8, Fig. 9 and shown in Figure 10, decorative cover enclosure wall 4 is connected with the periphery of airbag housing 6, capitate groove 4A on decorative cover enclosure wall 4 forms a plurality of buckle structures with a capitate 6B phase clamping on airbag housing 6, and the guide ledges 6C on airbag housing 6 inserts in guide groove 4B on decorative cover enclosure wall 4.
As shown in figure 11, when safety air bag point is quick-fried, safety air bag inflation in airbag housing 6 expands, thrust F1 promotes decorative cover, because airbag housing 6 maintains static, the peripheral shackle portion relative motion of decorative cover enclosure wall 4 and airbag housing 6 (dotted line direction motion as shown in Figure 7), wherein, a capitate 6B ramp produces F2 power and makes the capitate groove 4A of decorative cover strut.The capitate groove 4A of final decorative cover and the capitate of housing 6 6B break away from.
As shown in figure 12, due to square sipes 1 thin thickness of decorative cover, after a capitate 6B of the capitate groove 4A of decorative cover and airbag housing 6 breaks away from, square sipes 1 yield deformation, and as rotating shaft, decorative cover begins turning.Simultaneously, in the decorative cover switching process, two short line of weakness 2L and 2R on decorative cover tear.
