Abstract
Abstract This automotive bumper is a composite structure comprising a shield of synthetic material and a rigid reinforcing member having a S-shaped cross-sectional contour, disposed between the front portion of the shield and the plane of the front cross member of the vehicle chassis, said rigid member extending substantially throughout the width of said front portion, this bumper further comprising a pair of side flanges connecting in overhanging relationship the lower loop of said reinforcing member to said chassis cross member, said flanges being vertically and rigidly connected to one face of said cross member so that in case of shock said flanges are sheared about an axis substantially parallel to said chassis cross member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
157 words
A composite bumper of the shield type for vehicles having a chassis including a front cross member, which comprises an external shield of high-density synthetic material and a rigid reinforcing member, characterized in that said reinforcing member has an S-shaped cross-sectional configuration, only the lower loop of this S-shaped reinforcing member being adapted to engage the upper portion of the shield of synthetic material, said reinforcing member being disposed between the front portion of said shield and the plane of the front cross member of the chassis of the vehicle which extends substantially throughout the width of said front portion, said composite bumper further comprising a pair of side flanges connecting, in overhanging relationship, the lower loop of said reinforcing member to said chassis cross-member, said flanges being vertically rigid with one face of said cross member so that in case of shock said flanges are sheared about an axis substantially parallel to said chassis cross member.
Claim 2
Dependent Claim
157 words
A composite bumper of the shield type for vehicles having a chassis including a front cross member, which comprises an external shield of high-density synthetic material and a rigid reinforcing member, characterized in that said reinforcing member has an S-shaped cross-sectional configuration, only the lower loop of this S-shaped reinforcing member being adapted to engage the upper portion of the shield of synthetic material, said reinforcing member being disposed between the front portion of said shield and the plane of the front cross member of the chassis of the vehicle which extends substantially throughout the width of said front portion, said composite bumper further comprising a pair of side flanges connecting, in overhanging relationship, the lower loop of said reinforcing member to said chassis cross-member, said flanges being vertically rigid with one face of said cross member so that in case of shock said flanges are sheared about an axis substantially parallel to said chassis cross member.
Claim 3
Dependent Claim
62 words
Composite bumper according to claim 1, characterized in that at least one elastic pad acts as a distance-piece between the shield and the rigid reinforcing member in the inoperative condition of the assembly, so as to provide a sufficient gap between these two main component elements of the bumper whereby, in case of moderate shocks, only the shield undergoes an elastic deformation.
Claim 4
Dependent Claim
45 words
Composite bumper according to claim 1, characterized in that each side flange consists of a curved lateral plate and of a vertical front plate, said front plate alone being rigidly attached to the chassis cross member, said lateral plate being attached to said reinforcing member.
Claim 5
Dependent Claim
45 words
Composite bumper according to claim 1, characterized in that the upper loop of said S-sectioned rigid reinforcing member is provided at least partly with a coating layer adapted to improve its appearance and emphasize in a more aesthetic manner the upper contour of the shield.
