Abstract
To enable the inclination of the metal framework of a seat-back of a vehicle seat to be adjusted with respect to the metal framework of the seat-bottom of this seat, elements of these two frameworks are constituted in the form of curvilinear sectional bars (6, 7) nestable contiguously in one another and centered on the same transverse horizontal axis positioned close to the pivoting axis of the hips of a person sitting on the seat and an adjusting and locking mechanism (13, 14) is provided enabling the degree of mutual fitting into one another of these sectional bars to be adjusted as desired.
Claims8
A seat, comprising:
- a seat bottom having a framework including two transversally spaced, longitudinally extensive guide members which are arcuately curved about the same axis, that being a horizontally disposed axis which extends tranversally of the seat at a level and position approximating the expected disposition of the pivoting axis of the hips of the seat-user;
- and
- a back-rest having a framework including two transversally spaced, longitudinally extensive bars which are arcuately curved about said same axis;
- the back-rest being tilt-adjustably mounted to the seat bottom by having said bars telescopically, slidably, interfittingly mounted to respective of said guide members;
- and
- adjustment and lock means connected between said seat bottom and back-rest for selectively fixing the back-rest at a desired degree of tilt.
