Abstract
Abstract A hinge for motor vehicle hood, trunk lids or the like where a plurality of arms are connected by pivot-forming rivets and spacer rings are provided between the arms with at least one of the spacer rings being made of a thermoplastic material and the hinge being annealed after the setting of the rivet about which the thermoplastic spacer ring is located. As a result, prestressing of the thermoplastic spacer ring created by the rivet setting is relieved. Spacer rings are provided between the original head of each rivet and an adjacent one of said arms as well as at an opposite side of the adjacent arms. Furthermore, the thickness of the spacing ring located at the side of the adjacent arms opposite from the original rivet head is of a thickness approximately double that of the spacer ring that is located between the original rivet and said adjacent arm.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A motor vehicle hinge of the type used on a hood, trunk lid, or the like of a motor vehicle, comprising a plurality of rigid arms, spacer rings, at least one of which is formed of thermoplastic material, provided between the arms, and rivets extending through said rigid arms and spacer rings, said rivets being deformed in a manner holding adjacent surfaces of the arms and the at least one thermoplastic spacer ring in flush contact with one another, wherein prestressing of said thermoplastic spacer ring created by said deformation of the rivet holding said arms and thermoplastic spacer has been relieved by annealing of the hinge, whereby the arms are able to pivot while being substantially free of play.
Claim 2
Dependent Claim
120 words
A motor vehicle hinge of the type used on a hood, trunk lid, or the like of a motor vehicle, comprising a plurality of rigid arms, spacer rings, at least one of which is formed of thermoplastic material, provided between the arms, and rivets extending through said rigid arms and spacer rings, said rivets being deformed in a manner holding adjacent surfaces of the arms and the at least one thermoplastic spacer ring in flush contact with one another, wherein prestressing of said thermoplastic spacer ring created by said deformation of the rivet holding said arms and thermoplastic spacer has been relieved by annealing of the hinge, whereby the arms are able to pivot while being substantially free of play.
Claim 3
Dependent Claim
40 words
The hinge as in claim 1, wherein spacing rings made of thermoplastic material are provided between the original head of each rivet and an adjacent surface of one of said arms and at an opposite surface of said adjacent arm.
Claim 4
Dependent Claim
188 words
A motor vehicle hinge of the type used on a hood, trunk lid, or the like of a motor vehicle, comprising a plurality of rigid arms, spacer rings, at least one of which is formed of thermoplastic material, provided between the arms, and rivets extending through said rigid arms and spacer rings, said rivets being deformed in a manner holding adjacent surfaces of the arms and the at least one thermoplastic spacer ring in flush contact with one another, wherein prestressing of said thermoplastic spacer ring created by said deformation of the rivet holding said arms and thermoplastic spacer has been relieved by annealing of the hinge, whereby the arms are able to pivot while being substantially free of play, spacer rings made of thermoplastic material are provided between the original head of each rivet and an adjacent surface of one of said arms and at an opposite surface of said adjacent arm, wherein the thickness of the spacing ring located at said opposite side of said adjacent arm is approximately double the thickness of the spacing ring located between the original rivet head and the adjacent arm.
Claim 5
Dependent Claim
188 words
A motor vehicle hinge of the type used on a hood, trunk lid, or the like of a motor vehicle, comprising a plurality of rigid arms, spacer rings, at least one of which is formed of thermoplastic material, provided between the arms, and rivets extending through said rigid arms and spacer rings, said rivets being deformed in a manner holding adjacent surfaces of the arms and the at least one thermoplastic spacer ring in flush contact with one another, wherein prestressing of said thermoplastic spacer ring created by said deformation of the rivet holding said arms and thermoplastic spacer has been relieved by annealing of the hinge, whereby the arms are able to pivot while being substantially free of play, spacer rings made of thermoplastic material are provided between the original head of each rivet and an adjacent surface of one of said arms and at an opposite surface of said adjacent arm, wherein the thickness of the spacing ring located at said opposite side of said adjacent arm is approximately double the thickness of the spacing ring located between the original rivet head and the adjacent arm.
Claim 6
Dependent Claim
21 words
The hinge as in claim 1 or 3, wherein the arms of the hinge and the rivets are made of aluminum.
Claim 7
Dependent Claim
94 words
The hinge as in claim 1 or 3, wherein at least one of said arms is a mounting arm for fixed connection with a vehicle hood or trunk lid, said mounting arm being provided with rivet openings, the size of the openings for the rivets in the mounting arms being determined so that the mounting arm is connected rigidly to the rivet on a side adjacent a head formed during said rivet deformation, other of said arms connected to said mounting arm having rivet openings sized to enable pivoting thereof about a respective rivet.
Claim 8
Dependent Claim
43 words
The hinge according to claim 5, wherein some of said arms are connected to a securing plate for fixed connection with a body portion of said vehicle by pivot forming rivets in the same manner as the arms connected to said mounting arm.
