Abstract: A synchronous tilt control mechanism is provided for a chair. The chair includes a base, a seat, a back, a torsion spring, a first slide member and a second slide member. The base further includes a tilt control housing mounted thereon. The back includes a forwardly extending support member. The seat and back are pivotally attached to the tilt control housing. The torsion spring has a forwardly extending leg and a rearwardly extending leg. The forwardly extending leg is mounted to the tilt control housing. The seat slidably engages the support member by way of the first slide member, which is disposed on one of the seat and the support member. The support member slidably engages the rearwardly extending leg of the torsion spring by way of the second slide member, which is disposed on one of the support member and rearwardly extending leg. A downward movement of the seat causes the back to move downwardly and rearwardly against an upward force provided by the torsion spring.

Abstract: A chair includes a base, a backrest supported by the base, a seat support by the base, and a seat slidably mounted to the seat support. A seat adjustment device can be employed to allow for forward and rearward adjustment of the seat relative to the backrest.

Abstract: A vehicle body door check (10) includes a scissors assembly (20) and a keeper (48) received between a pair of elongated check arms (22,24) of the scissors assembly and operable under the bias of a spring (46) to hold an associated vehicle door in an open position upon engagement with a check formation (36).

Abstract: A upper track roller mechanism for an automotive vehicle sliding door is provided in which the upper track is formed as a generally U-shaped track member having centering mechanisms associated with it for preventing vertical movement of the roller into rubbing contact with upper or lower portions of the track. The centering mechanisms may include one or more chamfers formed on the outer wall of the track and a washer carried adjacent the roller in juxtaposition with the portion of the track.
