Abstract
Abstract A seat for an automobile or other vehicle includes a seat part and an adjable back-rest part. The two parts are connected pivotally by a linkage which includes an eccentric disc having a large ratio of diameter to thickness. The disc engages in a recess in the back-rest part and is mounted on the seat part for rotation whereby the inclination of the two parts can be adjusted without relative translational movement between the two parts.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
126 words
In a seat, means defining a seat part, means defining a back rest part, and linkage means interconnecting the seat part and the back rest part to enable pivotal adjustment of the inclination of the seat part relative to the back rest part, said linkage means comprising a part rigid with the seat part, a part rigid with the back rest part and having a recess therein, a rotatable eccentric disc having a large ratio of diameter to thickness and an operational surface which is complementary to and engages in the recess of said part rigid with the back rest part, and a slide member in which the eccentric disc is mounted and which is itself slidably mounted in the part rigid with the seat part.
Claim 2
Dependent Claim
126 words
In a seat, means defining a seat part, means defining a back rest part, and linkage means interconnecting the seat part and the back rest part to enable pivotal adjustment of the inclination of the seat part relative to the back rest part, said linkage means comprising a part rigid with the seat part, a part rigid with the back rest part and having a recess therein, a rotatable eccentric disc having a large ratio of diameter to thickness and an operational surface which is complementary to and engages in the recess of said part rigid with the back rest part, and a slide member in which the eccentric disc is mounted and which is itself slidably mounted in the part rigid with the seat part.
Claim 3
Dependent Claim
137 words
A seat according to claim 1, comprising two said linkage means, one said linkage means further comprising an annulus gear co-axial with the geometric centre of the eccentric disc and secured on the periphery of the eccentric disc, a hand grip, and a pinion mounted on the part rigid with the seat part, mounted for rotation with the hand grip and meshing with the annulus gear, the seat further comprising a shaft of polygonal cross-section, each eccentric disc having an aperture of complementary cross-section to the shaft and the eccentric discs being interconnected by engagement of the shaft in the complementary apertures whereby rotation of the hand grip of the one linkage will rotate the pinion and the annulus gear of that linkage and the rotation will be transmitted to the other linkage by the polygonal shaft.
