Abstract
Seat assemblies and subassemblies such as for a vehicle are disclosed. The subassemblies may include joint assembly with a motor configured to move the seat assembly from a first position to a second position via the coordination between a rotating spindle and ring disposed around the spindle. The joint assembly may move an occupant to a predetermined position such as the zero-gravity position for greater comfort during extended use or lengthy travel.
Claims20
A subassembly for varying a position of a seat comprising:
- an actuator assembled in a seat assembly and defining a rotary axis;
- a first guide in cooperation with the actuator and defining a translation axis;
- a second guide cooperating with the first guide;
- and
- a joint in cooperation with the first or second guide such that during actuation of the actuator the joint moves from a retracted position to an extended position and the first or second guide translates relative the translation axis.
2 more elements
A seat assembly comprising:
- a base;
- a seat frame disposed on the base and defining a seat bottom and/or seat back;
- a drive assembly having an actuator, the drive assembly moving the seat frame relative to the base from a first position to a second position;
- a first guide and a second guide operably connected to the first guide;
- and
- a joint on the base or the seat frame;
- wherein when the actuator drives the first or second guide, the translation of the first or second guide moves the seat frame to the first position or the second position.
4 more elements
A seat assembly comprising:
- a seat frame configured to be attached to a stationary base rail;
- and
- a joint assembly comprising:
- an actuator defining a rotary axis;
- a transmission cooperating with the actuator to rotate a first guide, the first guide being in communication with a second guide;
- and
- a joint cooperating with the first or second guide and being configured to be connected to the seat frame or the stationary base rail such that the first or second guide steers the other of the first or second guide from a first position to a second position, the first and second positions corresponding to a retracted position and an extended position of the joint, wherein the retracted position and extended position correspond to different seat frame positions.
