Abstract
Abstract A hinge mount assembly for motor vehicle seats includes at each lateral side of the seat an outer hinge mount member shaped with an embossed external gear meshing at one point with the internal gear. Both hinge mount members are supported on a rotary axle having an eccentric portion supporting the inner hinge mount member and thus forming a wobble gear inclination adjuster for the backrest. The axial compactness of both hinge mount assemblies of the seat is insured by bearing plates adjoining the inner hinge mount members and being interconnected above the pivot axle by a U-shaped attachment frame for the backrest and, below the pivot axle, by a transverse beam. In addition, each inner hinge mount member is rigidly connected to a reinforcing side strap which overlaps the outer surface of the outer hinge mount member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A hinge mount assembly for seats, particularly motor vehicle seats having a seat component and a reclinable backrest component, comprising a fixed hinge mount member secured to a lateral side of the seat component; a tiltable hinge mount member secured to the backrest component; a transverse pivot axle defining an intermediate eccentric portion and lateral concentric portions, said eccentric portion bearing on the fixed hinge mount member and one of said concentric portions supporting the tiltable hinge mount member, an attachment frame for the backrest component secured to said tiltable hinge mount member; a position adjuster including an outer gear formed on said fixed hinge mount member and an inner gear formed on said tiltable hinge mount member, said inner gear exceeding in diameter said outer gear and being in mesh therewith; and a bearing plate supported on the other concentric portion of the pivot axle and being connected to said attachment frame.
Claim 2
Dependent Claim
153 words
A hinge mount assembly for seats, particularly motor vehicle seats having a seat component and a reclinable backrest component, comprising a fixed hinge mount member secured to a lateral side of the seat component; a tiltable hinge mount member secured to the backrest component; a transverse pivot axle defining an intermediate eccentric portion and lateral concentric portions, said eccentric portion bearing on the fixed hinge mount member and one of said concentric portions supporting the tiltable hinge mount member, an attachment frame for the backrest component secured to said tiltable hinge mount member; a position adjuster including an outer gear formed on said fixed hinge mount member and an inner gear formed on said tiltable hinge mount member, said inner gear exceeding in diameter said outer gear and being in mesh therewith; and a bearing plate supported on the other concentric portion of the pivot axle and being connected to said attachment frame.
Claim 3
Dependent Claim
35 words
A hinge mount assembly as defined in claim 1, wherein the bearing plates assigned to respective tiltable hinge mount members at the two lateral sides of the seat component are interconnected by a transverse beam.
Claim 4
Dependent Claim
47 words
A hinge mount assembly as defined in claim 1, wherein said bearing plate has a projecting part exceeding the boundary of the adjoining fixed hinge mount member, said attachment frame being connected to said tiltable hinge mount member and to the projecting part of said bearing plate.
Claim 5
Dependent Claim
34 words
A hinge mount assembly as defined in claim 1, wherein said attachment frame has a U-shaped configuration and said bearing plates being integrally formed in the end portions of the arms of said frame.
Claim 6
Dependent Claim
58 words
A hinge mount assembly as defined in claim 4, wherein said bearing plates formed on said attachment frame adjoin, respectively, said fixed hinge mount member on each lateral side of the seat component and are rigidly connected to said tiltable hinge mount member above said pivot axle to form an interspace occupied by said fixed hinge mount member.
Claim 7
Dependent Claim
38 words
A hinge mount assembly as defined in claim 1, wherein said fixed hinge mount member is rigidly connected to a holding side strap which overlaps the outer surface of said tiltable hinge mount member below said pivot axle.
Claim 8
Dependent Claim
46 words
A hinge mount assembly as defined in claim 6, wherein said bearing plates and said holding straps are formed with embossed collar bushings and the corresponding hinge mount members are formed with fitting embossed cones engaging said bushings to provide connection points secured together by welding.
