[0001] The present disclosure relates, generally, to an airbag cover assembly, and more particularly relates to a driver airbag cover assembly configured to illuminate.BACKGROUND

[0002] Airbag systems are commonly used on vehicles and especially in steering wheels. These airbags are designed to inflate during an accident to prevent a driver from harmful impact with the steering wheel during a crash. Manufacturers of the vehicles place their logo / emblem on the airbag cover to enhance the styling and aesthetics of the airbag cover. Moreover, some logo / emblem have a metallic chrome portion for improved appearance.SUMMARY

[0003] One aspect of the disclosure is to provide an airbag cover assembly. The airbag cover assembly includes an airbag cover including a frontal wall defining a cavity and a plurality of apertures arrayed along a periphery of the frontal wall. The airbag cover includes a plurality of engagement structures.

The airbag cover assembly further includes a covering member arranged abutting the frontal wall of the cover and disposed covering the emblem structure. The covering member includes a plurality of protrusions having thermally formed heads arranged inside the plurality of apertures. The covering member also includes a plurality of retention structures mechanically engaged with the plurality of engagement structures.

[0004] Due to the dual engagement of the covering member with the airbag cover i.e., frontal wall and due to the thermal coupling of covering member with the airbag cover,sealing contact is formed between a rear surface of the covering member and a front surface of the frontal wall, preventing any leakage of light and illumination of the covering member except the area corresponding to the emblem. Moreover, the mechanical fastening of the covering member with the airbag cover via the engagement structures and the retention structures prevents a disengagement of the covering member from the airbag cover during assembly and prior to the thermal coupling of the airbag cover with the covering member.

[0005] The covering member allows a passage of light from an inside of the cover assembly to an outside of the cover assembly upon illumination of the emblem to enable a viewing of the emblem from the outside. Accordingly, the covering member remains dark when the emblem is not illuminated from inside, giving a phantom effect.

[0006] In some embodiments, the heads are thermally formed by a hot air cold staking process.

[0007] In some embodiments, the covering member includes an outer edge disposed aligned with an outer edge of the frontal wall of the airbag cover. This prevents leakage of light from the sides of the covering member and the airbag cover.

[0010] In some embodiments, a first surface of the emblem structure is arranged flush with the first surface of the frontal wall of the airbag cover to prevent any light leakage between the emblem structure and the frontal wall except the area corresponding to the emblem.

[0011] In some embodiments, the covering member is made of a translucent material to allow passing of the light through the covering member upon illumination of the emblem by the light source. This helps in keeping the covering member dark and prevent a viewing of internal features of the airbag cover assembly from an outside of the airbag cover assembly.

[0012] In some embodiments, the airbag cover includes a pair of tear lines disposed spaced apart and opposite to each other, wherein the cavity, the plurality of apertures, and the plurality of engagement structures are disposed inside a space defined between the pair of tear lines. As the airbag cover is torn along the tear lines as the airbag is deployed and inflated, the positioning of the cavity, the apertures and engagements structure between the tear lines ensure that the emblem structure and a portion of the covering member remains engaged with the airbag cover during deployment of the airbag preventing various components of the airbag cover assembly being thrown and flying independently of the airbag cover.

[0013] In some embodiments, the plurality of engagement structures includes a plurality of grooves and the plurality of retention structures includes a plurality of tabs extending inside the plurality of grooves to enable a snap fitting of the covering member with the airbag cover.

[0014] In some embodiments, the airbag cover defines a plurality of slots and the emblem structure includes a plurality of projections arranged inside the plurality of slots with ends of the plurality of projections arranged inside the plurality of slots includes thermally formed heads. In some embodiments, the heads are thermally formed by a hot air cold staking process.

The method further includes engaging the plurality of retention structures of the covering member blank with the plurality of engagement structures of the airbag cover and inserting the plurality of pins inside the plurality of apertures upon coupling the emblem structure blank with the airbag cover. Moreover, the method includes positioning the airbag cover assembly on a jig such that the first surface of the frontal wall of the airbag cover is arranged underneath the second surface of the airbag cover, and thermally forming an end of each of the plurality of pins arranged inside the plurality of apertures into a head to prevent a removal of the covering member from the airbag cover.

[0016] In some embodiments, the thermal forming includes a hot air cold staking process.

[0017] The mechanical fastening of the covering member with the airbag cover via the engagement structures and the retention structures prevents a disengagement of the covering member from the airbag cover during assembly and prior to the thermal coupling of the airbag cover with the covering member.

[0018] In some embodiments, coupling the emblem structure blank with the airbag cover includes inserting a plurality of projection pins of the emblem structure blank inside a plurality of slots of the airbag cover and thermally forming an end of each of the plurality of projection pins arranged inside the plurality of slots of the airbag cover into a head to prevent a removal of the emblem structure blank from the airbag cover.

[0040] The emblem structure 160 includes a plurality of projections 180 extending rearwardly from a rear surface of the flat body 162 and extending inside the slots 174. As shown, each projection 180 includes an elongated rod 182 extending inside the elongated portion 176 of the slot 174 and a head / retaining member 184 arranged inside the head portion 178 of the associated slot. It may be appreciated the heads 184 are thermally formed heads formed during attachment of the emblem structure 160 with the rear wall 122 i.e., airbag cover 102 by a thermal forming process, for example, a hot air cold staking process (HACS). The thermally formed heads 184 prevent the removal of the projections 180 from the slots 174, thereby preventing the disengagement of the emblem structure 160 from the airbag cover 102. Also, the flat body 162 is made of substantially opaque material, while the emblem 170 is made of translucent material or transparent material. The translucent or transparent material allows the illumination of the emblem 170 when the light source 172 is switched on / activated. It may be appreciated that the light source 172 may be activatedautomatically upon starting of the vehicle or pressing or insertion of start key of the vehicle.

[0041] Further, referring to FIGS. 2, 4, and 8, to cover the frontal wall 104 and the emblem structure 160, the airbag cover assembly 100 includes a covering member 190 attached to the frontal wall 104 i.e., airbag cover 102. As shown, the covering member 190 includes an outer edge 192 aligned with the outer edge 118 of the frontal wall 104 i.e., airbag cover 102, as shown in FIG. 2. As shown, the outer edge 192 includes a pair of longitudinal edges 250, 252 that are arranged aligned with the pair of longitudinal edges 110, 112 of the airbag cover 102, and a pair of lateral edges 254, 256 arranged aligned with the pair of lateral edges 114, 116 of the airbag cover 102. In some embodiments, the lateral edges 254, 256 of the covering member 190 may extend beyond the lateral edges 114, 116 of the airbag cover 102.

[0042] To enable the attachment of the covering member 190 with the frontal wall 104 i.e., airbag cover 102, as shown in FIG. 6 and FIG. 8, the covering member 190 includes a plurality of protrusions 194 having an elongated rod portion 196 and heads / retaining members 198 arranged at the ends of the protrusions 194. In the assembly of the covering member 190 with the frontal wall 104 i.e., airbag cover 102, the elongated rod portions 196 extend inside the elongated portions 134 of the apertures 130, while the heads 198 are arranged inside the head portions 136 of the apertures. It may be appreciated that the heads 198 are thermally formed heads formed during attachment of the covering member 190 with the frontal wall 104 i.e., airbag cover 102 by athermal forming process, for example, a hot air cold staking process (HACS). The thermally formed heads 198 prevent the removal of the protrusions 194 from the apertures 130, thereby preventing the disengagement of the covering member 190 from the airbag cover 102.

[0043] Further, the covering member 190 includes a plurality of retention structures 220, shown in FIG. 8, mechanically engaged with the plurality of engagementstructures 140. In the illustrated embodiment, each retention structure 220 includes a hook shaped tab 222 that engages with the groove 142 of the airbag cover 102. The tabs 222 are snap fitted with the grooves 142 of the airbag cover 102. The dual connection of the covering member 190 with the frontal wall 104 i.e., airbag cover 102 prevents any leakage of the light from the outer edge 192 of the covering member 190 as well as prevent the leakage of light between the first surface 108 of the frontal wall 104 and a rear surface 224 of the covering member 190 as well as between the flat body 162 of the emblem structure 160 and the rear surface 224 of the covering member 190. This is achieved as the rear surface 224 of the covering member 190 is arranged in abutment with the first surface 108 of the frontal wall 104 and the flat body 162 of the emblem structure 160 due to the thermally formed connection and the dual connection of the covering member 190 and the frontal wall 104. Also, the covering member 190 is made of a suitable material that allows a passage of light from an inside of the airbag cover assembly 100 to an outside of the airbag cover assembly 100 upon illumination of the emblem 170 to enable a viewing of the emblem 170 from the outside. However, the covering member 190 prevents a viewing of an inside of the airbag cover assembly 100 due to illumination from a light source 172 arranged outside of the airbag cover assembly 100. Accordingly, the covering member 190 remains dark when the light source 172 is switched off, making the emblem 170 invisible.

[0044] A method for assembling / forming the airbag cover assembly 100 is now explained. The method includes coupling an emblem structure blank 160’ (shown in FIG. 9) with the airbag cover 102. It may be appreciated that the emblem structure blank 160’ is similar to the emblem structure 160 except that emblem structure blank 160’ includes a plurality of projection pins 180’ instead of the plurality of projections 180. It may be appreciated that the plurality of projection pins 180’ is thermally formed into the plurality of projections 180 during the coupling of the emblem structure blank 160’ with the airbag cover 102. For coupling the emblem structure blank 160’ with the airbag cover 102, the emblem structure blank 160’ is arranged inside the cavity 120 ofthe airbag cover 102 such that the first surface 164 of the emblem structure blank 160’ is arranged flush with the first surface 108 of the frontal wall 104 of the airbag cover 102, and the plurality of projection pins 180’ extends inside the plurality of slots 174 with free end portions of the projection pins 180’ disposed inside the head portions 178 of the slots 174. Upon inserting the plurality of projection pins 180’ inside the plurality of slots 174, the free ends of projection pins 180’ are thermally formed into heads 184 by using the hot air cold staking process to achieve a firm coupling of the emblem structure 160 with the airbag cover 102.

[0045] Subsequently, a covering member blank 190’ (shown in FIG. 10) is coupled to the airbag cover 102. It may be appreciated that the covering member blank 190’ is similar to the covering member 190 except that the covering member blank 190’ includes a plurality of pins 194’ instead of the plurality of protrusions 194. It may be appreciated that the plurality of pins 194’ is thermally formed into the plurality of protrusions 194 during the coupling of the covering member blank 190’ with the airbag cover 102. For coupling the covering member blank 190’ with the airbag cover 102, the plurality of retention structures 220 of the covering member blank 190’ is engaged with the plurality of engagement structures 140 of the airbag cover 102 i.e., the tabs 222 are inserted inside the grooves 142 and the coupled with the frontal wall 104. In so doing, the plurality of pins 194’ is also extended / inserted inside the plurality of apertures 130 such that the free end portions of the pins 194’ are arranged inside the head portions 136 of the apertures 130. The mechanical engagement of the tabs 222 with the grooves 142 prevents a disengagement of the covering member blank 190’ from the airbag cover 102, and hence the removal of pins 194’ from the plurality of apertures 130, during transfer of the assembly to jig. Thereafter, the airbag cover assembly 100 is positioned on the jig such that the first surface 108 of the airbag cover 102 is arranged underneath the second surface 132 of the airbag cover 102, and ends of the pins 194’ are thermally formed into heads 198 by using the hot air cold staking process.
