Abstract
Abstract A light-transmitting plastics shield 1 is provided with distance pieces 5 for attachment to the lens 2 of a headlamp, each distance piece comprising a male part 6 and a female part 7, the male part being ultrasonically welded to the shield and comprising a cylindrical head 12 supported between spaced walls 10, 11, the female part 7 comprising a disc-shaped base 14 carrying a socket portion 16, and the base being secured to the lens by an adhesive foam pad 15. The heads 12 are received within the socket portions 16 and are mounted with their axes parallel to allow the shield to be pivoted away from the lens for cleaning. The heads are also capable of axial movement within the sockets to allow for thermal expansion of the shield.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A device for protecting the light-emitting face of a vehicle lamp assembly, said face having a peripheral edge, comprising: a light transmitting shield in the form of a sheet of plastics material for covering at least a portion of said face and protecting said face from impact damage; a plurality of mutually spaced distance pieces secured to said shield for spacing said shield from said face in use, each distance piece comprising a releasable two part connector; and an adhesive for attachment of said distance pieces to said face, said distance pieces being arranged for attachment directly to said light-emitting face at positions inset from the peripheral edge thereof.
Claim 2
Independent Claim
109 words
A device for protecting the light-emitting face of a vehicle lamp assembly, said face having a peripheral edge, comprising: a light transmitting shield in the form of a sheet of plastics material for covering at least a portion of said face and protecting said face from impact damage; a plurality of mutually spaced distance pieces secured to said shield for spacing said shield from said face in use, each distance piece comprising a releasable two part connector; and an adhesive for attachment of said distance pieces to said face, said distance pieces being arranged for attachment directly to said light-emitting face at positions inset from the peripheral edge thereof.
Claim 3
Dependent Claim
24 words
