<p>Dynamic seat comprised of a frame (2) which receives the horizontal motionless part of the seat. Said frame comprises two substantially vertical arms (3) at the end of which is mounted the oscillating frame (5) of the back (6). Adjustable means such as springs acting as a return spring are secured between the frame (5) and the frame (2) so as to provide for the angular adjustment of the back (6). The upper part of the frame (5) comprises a cylinder (8) on which is mounted the armature (10) of the headrest (32). Its connection with the frame is provided by servo-control means (11, 14). Locking means (23, 24) enable the user to block the pivoting of the seat as desired. The seat may or may not be provided with a horizontal part (1) on which may be mounted sides (33, 34) to provide for a better comfort. This invention applies particularly to motor vehicles, space vehicles, as well as to furniture.</p> |
