Abstract
Abstract A protective bumper for a vehicle which may be shaped in the form of an airfoil so that air passing over the bumper produces an aerodynamic reaction normal to its direction of movement which causes a downwardly directed thrust to be transmitted to the vehicle. The bumper may comprise at least one main body portion and at least one secondary portion, the latter being movable relatively to the main body portion upon being subjected to an impact loading and returning to the original position upon removal of the loading. The bumper may be mounted on a vehicle by means of mountings provided with flange means imbedded in a compressible material contained in a housing having internal flange means of helical configuration. Further disclosed is a bumper formed of bent timber and a method of forming such bumper by heating and moistening the timber, bending the timber to the required shape and then drying.

Claim 1
Independent Claim
68 words
A vehicle having a protective bumper and bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a housing having internal flange means both sets of flange means being spaced from each other by the compressible material, and wherein the support arm flange means aNd housing flange means each comprise a flange of helical configuration.
Claim 2
Dependent Claim
68 words
A vehicle having a protective bumper and bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a housing having internal flange means both sets of flange means being spaced from each other by the compressible material, and wherein the support arm flange means aNd housing flange means each comprise a flange of helical configuration.
Claim 3
Dependent Claim
69 words
A vehicle having a protective bumper and bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a housing having internal flange means both sets of flange means being spaced from each other by the compressible material and, wherein the support arm flange means and housing flange means each comprise a plurality of spaced annular flanges.
Claim 4
Dependent Claim
69 words
A vehicle having a protective bumper and bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a housing having internal flange means both sets of flange means being spaced from each other by the compressible material and, wherein the support arm flange means and housing flange means each comprise a plurality of spaced annular flanges.
Claim 5
Dependent Claim
95 words
A vehicle having a protective bumper and a pair of bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a respective pair of housings each having a closed end and internal flange means both sets of flange means being spaced from each other by the compressible material, and wherein the housing is of frusto-conical configuration and frictionally engages an outer housing of similar configuration a space being formed between the closed ends of the two housings which accommodates a compressible material.
Claim 6
Dependent Claim
95 words
A vehicle having a protective bumper and a pair of bumper support arms which at their respective mountings to the vehicle are provided with flange means embedded in a compressible material contained in a respective pair of housings each having a closed end and internal flange means both sets of flange means being spaced from each other by the compressible material, and wherein the housing is of frusto-conical configuration and frictionally engages an outer housing of similar configuration a space being formed between the closed ends of the two housings which accommodates a compressible material.
Claim 7
Dependent Claim
39 words
A vehicle as claimed in claim 3, wherein said outer housing is mounted on the vehicle by fastening means which permit limited movement of the housing in the event of the bumper being subjected to a high impact force.
