Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
116 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bentaround end portions extending approximately parallel to the outer surface of the body, characterized in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by a guide means, and in that said guide means include a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of each bumper end portion, and further characterized in that the connection between the end portions and the center section takes place by bent spring means.
Claim 2
Dependent Claim
116 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bentaround end portions extending approximately parallel to the outer surface of the body, characterized in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by a guide means, and in that said guide means include a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of each bumper end portion, and further characterized in that the connection between the end portions and the center section takes place by bent spring means.
Claim 3
Dependent Claim
111 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bent-around end portions extending approximately parallel to the outer surface of the body, characterizied in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by guide means, and in that said guide means includes a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of each bumper end portion, and further characterized in that a hinge-like connection exists between the end portions and the center section.
Claim 4
Dependent Claim
111 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bent-around end portions extending approximately parallel to the outer surface of the body, characterizied in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by guide means, and in that said guide means includes a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of each bumper end portion, and further characterized in that a hinge-like connection exists between the end portions and the center section.
Claim 5
Dependent Claim
107 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bent-around end portions extending approximately parallel to the outer surface of the body, characterized in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by guide means, and in that said guide means include a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of said bumper end portion, and further characterized in that the bumper is displaceable in the longitudinal direction.
Claim 6
Dependent Claim
107 words
A bumper for motor vehicles which is displaced in case of an impact and which includes a center section and lateral bent-around end portions extending approximately parallel to the outer surface of the body, characterized in that the end portions are movably connected with the center section and are substantially longitudinally displaceably guided at a distance from the body by guide means, and in that said guide means include a spacer means projecting from the body which spacer means engages in a guide rail means mounted on the inside of said bumper end portion, and further characterized in that the bumper is displaceable in the longitudinal direction.
