Abstract
Abstract In combination a vehicle bumper comprising a rigid support beam covered with a resilient elastomeric impact energy absorbing body and a lamp assembly housed within the bumper. The lamp assembly having a body and lens assembly telescopically mounted on housing supported within the beam and normally biased to telescopically project into the energy absorbing body. Upon impact causing the energy absorbing body to abut the lamp body and lens assembly, the latter is telescopically retracted relative to the housing against the resistance of the biasing force. After the deflecting load is released, the lamp body and lens are biased to their normal extended relationship to the housing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
In combination, a vehicle bumper comprising a hollow rigid support beam having a resiliently deformable impact energy absorbing body extending over the impact face of the beam; the impact face of the beam and the energy absorbing body covering the same having axially aligned openings therethrough; and a lamp assembly mounted within the bumper; the lamp assembly comprising a housing secured to the beam interiorly of the latter in axial alignment with the opening therein; a lamp body; the housing and lamp body being telescopically slidable relative to one another; a lens mounted on the lamp body; and a biasing means between the housing and the lamp body normally maintaining the two telescopically extended; the lamp body and lens when in telescopically extended relation to the housing projecting through the impact face of the support beam into the opening in the energy absorbing body; the energy absorbing body upon impact deflection toward the support beam in the area of the lamp body causing the lamp body and lens to retract into the housing against resistance of the biasing means; the biasing means being operative to restore the lamp body and lens to extended relationship to the housing after the deflecting load has been removed.
Claim 2
Dependent Claim
204 words
In combination, a vehicle bumper comprising a hollow rigid support beam having a resiliently deformable impact energy absorbing body extending over the impact face of the beam; the impact face of the beam and the energy absorbing body covering the same having axially aligned openings therethrough; and a lamp assembly mounted within the bumper; the lamp assembly comprising a housing secured to the beam interiorly of the latter in axial alignment with the opening therein; a lamp body; the housing and lamp body being telescopically slidable relative to one another; a lens mounted on the lamp body; and a biasing means between the housing and the lamp body normally maintaining the two telescopically extended; the lamp body and lens when in telescopically extended relation to the housing projecting through the impact face of the support beam into the opening in the energy absorbing body; the energy absorbing body upon impact deflection toward the support beam in the area of the lamp body causing the lamp body and lens to retract into the housing against resistance of the biasing means; the biasing means being operative to restore the lamp body and lens to extended relationship to the housing after the deflecting load has been removed.
Claim 3
Dependent Claim
34 words
In combination, according to claim 1, in which: the lamp assembly housing is of substantially rectangular tubular cross section; and the lamp body is of substantially complementary cross-sectional shape and slidable within the housing.
Claim 4
Dependent Claim
184 words
In combination, a vehicle bumper comprising a rigid box support beam substantially concealed within a resiliently deformable elastomeric impact energy absorbing body; an axial opening extending from a vertical impact face of the energy absorbing body concealing the support beam; the lamp assembly mounted within the bumper; the lamp assembly comprising a substantially tubular housing fixedly mounted within the support beam in axial alignment with the opening in the bumper energy absorbing body; a lamp body telescopically slidable in the housing; a lens mounted on the lamp body; and spring means between the housing and the lamp body normally maintaining the two telescopically extended; the lamp body and lens when in telescopically extended relation to the housing projecting from within the support beam into the energy absorbing opening; the energy absorbing body upon impact deflection into engagement with the lamp body and lens causing the latter to retract into the housing against the resistance of the biasing means; the biasing means after the deflecting load is released being effective to restore the lamp body and lens to a normal extended relationship to the housing.
Claim 5
Dependent Claim
184 words
In combination, a vehicle bumper comprising a rigid box support beam substantially concealed within a resiliently deformable elastomeric impact energy absorbing body; an axial opening extending from a vertical impact face of the energy absorbing body concealing the support beam; the lamp assembly mounted within the bumper; the lamp assembly comprising a substantially tubular housing fixedly mounted within the support beam in axial alignment with the opening in the bumper energy absorbing body; a lamp body telescopically slidable in the housing; a lens mounted on the lamp body; and spring means between the housing and the lamp body normally maintaining the two telescopically extended; the lamp body and lens when in telescopically extended relation to the housing projecting from within the support beam into the energy absorbing opening; the energy absorbing body upon impact deflection into engagement with the lamp body and lens causing the latter to retract into the housing against the resistance of the biasing means; the biasing means after the deflecting load is released being effective to restore the lamp body and lens to a normal extended relationship to the housing.
Claim 6
Dependent Claim
34 words
In combination, according to claim 3, in which: the lamp assembly tubular housing is of substantially rectangular cross section; and the lamp body is of substantially complementary cross-sectional shape and slidable within the housing.
