An ultra compact, easy to operate folding vehicle seat includes a seat back, seat base and support leg members and is movable between a stow position and a design position. The folding vehicle seat includes a folding mechanism having an upper member for connection to the seat back and a lower member for supporting the seat base; the upper and lower members of the folding mechanism include integrated teeth aligned in meshing relationship such that movement of the seat back causes the lower member to rotate and lift the seat base to move the folding vehicle seat to a design position. A pair of upper cams are provided for selective engagement with the upper member and a third cam tab of the lower member of the folding mechanism.

A recliner mechanism for a vehicle seat includes a toothed sector member secured to a seat frame and first and second pivoted pawl members each including a plurality of teeth to engage the teeth of the sector member. The first and second pawl members also each pivot on a cam pin member located at a distal end thereof, the cam pins each have a center axis and an offset axis having by a toothed cam lobe. The toothed cam lobes mesh such that rotation of one cam pin member causes the other cam pin member to totate in the opposite direction. A handle is coupled to at least one of the cam pin members to rotate the cam pin members and cause the pawl members to rotate about a pin connecting the proximal ends of the pawl members. The pawl members are movable between a first or locked position and a second or unlocked position, permitting the seat back to be adjusted with respect to the seat base against the force of a spring.
摘要:
A rail guide that has at least one rail pair consisting of a floor rail (22) and a seat rail (24). The seat rail (24) has connectors (30) for fastening a seat frame to be arranged above the rail pair. The rails can be moved relative to each other in a longitudinal direction along a movement path (20). The floor rail (22) and the seat rail (24) are curved by the same circular radius of curvature (42) that ranges between 1,500 and 3,000 mm, in particular between 1,800 and 2,500 mm. The center point of curvature (44) is on the side of the rail pair facing away from the seat frame. The rail guide is a longitudinal adjustment device having a stationary spindle (52) and an associated spindle nut (54) that is longitudinally movable thereon, the spindle (52) being curved at the same circular radius of curvature (42). Also described is a suitable method for producing said curved rails by at least one stamping mold (68) or by bending strips (96).

摘要:
An arrangement for a 4-bar system of a stowable vehicle seat to allow the 4-bar system to move over-center without binding, with the 4-bar system including a grounded leg, a rear leg, a cushion member and a front leg. The arrangement comprises a cam coupled to the front leg. A stop pin is mounted on the cushion member and aligned to engage the cam. An elongated slot is defined in the cushion member and configured to receive a pivot pin coupled to the front leg. A release lever is defined on the front leg and configured to contact the cam. As the 4-bar system goes over-center, the cam pivots away from the stop allowing the front leg to move in the slot as the vehicle seat is stowed. This freedom of motion, allows the vehicle seat to go over-center during the stowing procedure.
摘要:
A vehicle seat assembly having an integral child seat and a seat back which is rotatably mounted. An interlock is provided between the child seat and a latch for the rotating seat back to prevent release of the seat back latch when the child seat has been deployed and conversely, when the seat back latch has been released, the interlock prevents deployment of the child seat.
摘要:
A collapsing truss that completes a four-bar mechanism of a vehicle seat coupled to a vehicle floor. The vehicle seat includes a seat back coupled to a cushion structure via the collapsing truss which incorporates a pivot and a latch which engages on a pin. The collapsing truss includes a floor bracket coupled to the vehicle floor. A seat back bracket is coupled to the seat back and floor bracket. A cushion bracket is pivotally coupled to the cushion structure, the floor bracket, and the seat back bracket. The joints of the collapsing truss are defined by the seat back pivot, the cushion back/seat back bracket pivot, and the latch engagement pin. The seat back moves about the pivot when the collapsing truss operates.
摘要:
An apparatus for reducing rattle in an automotive seat release mechanism includes a torsion spring applying both a rotational force and a linear force to a cross member operatively connecting a first release and a second release. The spring force biases the cross member toward the second release linearly, and biases the cross member in a first rotational direction to reduce rattle between the cross member and components connecting the cross member to the first and second releases.
