Abstract

Aspects of the disclosure relate to a front grille and a motor vehicle hood assembly, as well as methods of installing the front grille to the hood assembly. The front grille includes a peripheral frame with left and right members and a plurality of fasteners extending rearward from the left member and the right member. The hood assembly includes medially extending tab members and insertion gaps arranged proximate to left and right sides of a front aperture defined in the hood assembly. Each tab member is separated from each other tab member by at least one of the insertion gaps. During mounting, the plurality of fasteners of the front grille are inserted into the insertion gaps, and the front grille is slid upward relative to the hood assembly, causing the fasteners to slidably engage the tab members. Sliding engagement of the fasteners reduces stress on the front grille from hood deflection.

First claim

What is claimed is:

1 . A front grille for a motor vehicle, the front grille comprising:
a peripheral frame including left and right members, and defining a central opening; and a first plurality of fasteners extending rearward from the left member, and a second plurality of fasteners extending rearward from the right member, wherein the first plurality of fasteners and the second plurality of fasteners are configured for sliding engagement with a hood assembly of the motor vehicle.

2 . The front grille of claim 1 , further comprising a grating disposed in the central opening extending between the left and right members of the peripheral frame.

3 . The front grille of claim 1 , wherein the peripheral frame further comprises a top member and a bottom member each extending between the left and right members, wherein the left, right, top, and bottom members form a generally rectangular shape.

4 . The front grille of claim 3 , further comprising a plurality of upper attachment holes defined in the top member and a plurality of lower attachment holes defined in the bottom member.

5 . The front grille of claim 1 , wherein:
each fastener of the first plurality of fasteners comprises a left mount extending rearward from the left member and a left engagement feature attached to and extending upward from a rear wall of the left mount; and each fastener of the second plurality of fasteners comprises a right mount extending rearward from the right member and a right engagement feature attached to and extending upward from a rear wall of the right mount.

6 . The front grille of claim 5 , wherein:
each fastener of the first plurality of fasteners comprises a left slot defined between the left member and the left engagement feature; each fastener of the second plurality of fasteners comprises a right slot defined between the right member and the right engagement feature; and each left slot and each right slot is configured to slidably receive a portion of the hood assembly of the motor vehicle therein.

7 . The front grille of claim 6 , wherein each left engagement feature and each right engagement feature comprises a spring clip configured to exert a biasing force on a portion of the hood assembly that serves to reduce forward-rearward separation between the front grille and the hood assembly of the motor vehicle.

8 . The front grille of claim 7 , wherein the spring clip comprises a recurved shape that defines a forwardly extending engagement portion configured to contact the hood assembly of the motor vehicle.

9 . The front grille of claim 7 , wherein each of the left mount and the right mount includes a top surface defining an opening configured to receive at least a portion of the spring clip to promote attachment of the spring clip to the respective mount.

10 . A hood assembly for a motor vehicle, the hood assembly comprising:
at least one structural member defining a front aperture bounded by left and right sides; a plurality of first medially extending tab members and a plurality of first insertion gaps each arranged proximate to the left side of the front aperture, wherein each first medially extending tab member of the plurality of first medially extending tab members is separated from each other first medially extending tab member by at least one first insertion gap of the plurality of first insertion gaps; and a plurality of second medially extending tab members and a plurality of second insertion gaps each arranged proximate to the right side of the front aperture, wherein each second medially extending tab member of the plurality of second medially extending tab members is separated from each other second medially extending tab member by at least one second insertion gap of the plurality of second insertion gaps; wherein each insertion gap of the plurality of first insertion gaps and the plurality of second insertion gaps is configured to receive a fastener extending rearwardly from a front grille during a grille mounting operation, with the front grille being arranged to cover the front aperture; and wherein each medially extending tab member of the plurality of first medially extending tab members and the plurality of second medially extending tab members is configured to slidably engage the fastener extending rearwardly from the front grille.

11 . The hood assembly of claim 10 , wherein the front aperture is further bounded by an upper side defined by the at least one structural member.

12 . The hood assembly of claim 11 , further comprising a plurality of upper attachment holes defined in the at least one structural member along the upper side to receive upper fasteners for mounting the front grille to the hood assembly.

13 . The hood assembly of claim 10 , wherein the at least one structural member further comprises a lower opening extending between a bottom of the left side of the front aperture and a bottom of the right side of the front aperture.

14 . The hood assembly of claim 13 , further comprising a lateral support that is rearwardly offset relative to a front surface of the at least one structural member, wherein the lateral support is arranged behind the lower opening.

15 . The hood assembly of claim 14 , wherein the lateral support comprises a plurality of mounting brackets configured to receive lower fasteners for mounting the front grille to the hood assembly.

16 . The hood assembly of claim 10 , wherein the at least one structural member comprises a unitary structural member encompassing a left fender portion, a right fender portion, and a hood portion extending between and generally above the left fender portion and the right fender portion.

17 . The hood assembly of claim 16 , wherein the front aperture extends between the left fender portion and the right fender portion, and extends below the hood portion.

18 . The hood assembly of claim 10 , wherein each medially extending tab member of the pluralities of first and second medially extending tab members comprises a rearwardly protruding segment arranged proximate to a bottom edge of the medially extending tab member to promote retention of the fastener of the front grille.

19 . A method for mounting a front grille to a motor vehicle hood assembly including at least one structural member defining a front aperture bounded by left and right sides, the method comprising:
inserting a first plurality of fasteners extending rearward from a left member of a peripheral frame of the front grille with a plurality of first insertion gaps arranged proximate to the left side of the front aperture, and inserting a second plurality of fasteners extending rearward from a right member of the peripheral frame of the front grille with a plurality of second insertion gaps arranged proximate to the right side of the front aperture; and sliding the front grille upward relative to the motor vehicle hood assembly to position the front grille to cover the front aperture, to cause the first plurality of fasteners to engage a first plurality of medially extending tab members arranged proximate to the left side of the front aperture, and to cause the second plurality of fasteners to engage a second plurality of medially extending tab members arranged proximate to the right side of the front aperture.

20 . The method of 19 , further comprising:
fastening a top member of the front grille to the at least one structural member proximate to an upper edge bounding the front aperture.

21 . The method of 19 , further
