Patent number: 6447066Abstract: A device for adjusting a double-jointed seatback by a single control. A seat pan structure is joined on at least one side to a convex toothed sector centered on a first joint. A seatback structure is joined to two arms that extend on either side of a housing. The arms are articulated on a second joint mounted upon the housing, and are joined to a concave toothed sector centered on the second joint.

Patent number: 5961088Abstract: A device for securing and adjusting the lengthwise position of a removable and reversible seat for a vehicle. The device includes a pair of C-shaped tracks secured to the floor of the vehicle with each track having an upper compartment and a lower compartment. The upper compartment of each track accommodates a slider that is connected to each leg of the seat of the vehicle and includes a locking device having teeth. The slider is displaceable relative to the track so that the slider can be manipulated between a locked position and an unlocked position. The lower compartment accommodates a plate having parallel rows of perforations that are engaged by the teeth of the locking device in the locked position and are released from engagement in the unlocked position. The configuration of the track and slider arrangement provide the device with a strong leg-slider connection as well as good resistance to tearing free from the floor of the vehicle in case of impact.Type: GrantFiled: July 15, 1998Date of Patent: October 5, 1999Assignee: Irausa Ingeniera, S.A.Inventors: Jean-Pierre Chabanne, Jean Duchateau
