In a vehicle seat, a movable frame provided at a front end portion of a stationary frame is configured to be slidable frontward and rearward between a first position and a second position frontward of the first position. An outer covering provided to extend frontward from an upper side of the stationary frame is configured to wrap around a front end portion of the movable frame. First and second straps are provided to extend rearward from a front end of the outer covering and configured to pull the front end of the outer covering rearward. The front end of the outer covering from which the first and second straps extend is arranged under the stationary frame. The first strap and the second strap are in positions spaced out laterally from each other. The first strap and the second strap are being pulled laterally inward.

A vehicle seat comprising a stationary frame, a movable frame and a cushion pad is disclosed. The movable frame is provided at a front end portion of the stationary frame and configured to be slidable frontward and rearward between a first position and a second position that is frontward of the first position. The cushion pad is provided to extend frontward from an upper side of the stationary frame and configured to wrap around a front end portion of the movable frame. The movable frame has an upper surface including a curved surface bulging upwardly.

An articulation mechanism for coupling a pivoting backrest to a traveling seat pan frame includes a first link having a first end section attachable to a pivoting backrest, and a second end section connected to the first end section, the second end section having multiple holes. A second link has a first end section and a second end section connected together, the first end section of the second link having at least one hole aligned with one of the multiple holes of the second section of the first link, the second end section of the second link is pivotally attachable to a seat pan frame. A fastener pivotally attaches the second link to the first link via the at least one hole of the second link and the selected aligned one of the multiple holes of the second end section of the first link based on a hole combination chosen to achieve a predetermined ratio of backrest recline to seat pan travel.

A fold and dive seat for a vehicle that achieves a fatigue reduction posture is provided. The seat includes a tip up-extension mechanism that enable stipping-up and extension of the front end of a seat cushion and a seatback reclining mechanism for the fold and dive seat so that tipping-up for lifting the front end of the seat cushion and extension for extending the front end forward are performed simultaneously performed when the seatback reclining is performed.

A seat component adjustment actuator (1) comprises a housing, an electric motor (5), and a gearing (10) coupled to the electric motor (5) and comprising at least three worm transmission stages (11-16). A first worm transmission stage (11, 12) comprises a first worm (11) and a first worm gear (12) engaged with the first worm (11). A third worm transmission stage (15, 16) comprises a third worm (15) and a third worm gear (16) engaged with the third worm (15). The first worm (11) is supported in the housing such that the first worm (11) is rotatable about an input rotation axis. The third worm gear (16) is supported in the housing such that the third worm gear (16) is rotatable about an output rotation axis which is transverse to the input rotation axis.

An occupant-support base includes a seat pan and a seat pad. The seat pan and the seat pad cooperate to support an occupant thereon. The seat pad includes a fixed portion and a movable portion that is configured to move relative to the fixed portion.

A seat assembly includes a seat frame, a sub frame, an electric motor, a transmission, and a flexible drive shaft. The seat frame includes a front support portion and supports a bottom cushion. The sub frame has a top plate and a base plate. The top plate supports a front cushion and rotatably supports a screw gear. The electric motor includes a first output member and is fixedly mounted to the front support portion of the seat frame. The transmission includes an input member and a second output member. The transmission is fixedly mounted to the base plate of the sub frame. The second output member of the transmission is drivingly connected to the screw gear of the sub frame. The flexible drive shaft is drivingly connecting the first output member of the electric motor to the input member of the transmission.

A vehicle seating assembly includes a frame and an articulating flexmat assembly operably coupled with the frame. The articulating flexmat assembly includes an upper flexmat extending from a first side of the frame to a second side of the frame and a lower flexmat extending from the first side of the frame to the second side of the frame. The upper flexmat includes an upper static portion and an upper dynamic portion disposed above the upper static portion and adjustable by upper linear actuators that draw the upper dynamic portion toward the upper static portion to arc the upper flexmat outward. The lower flexmat includes a lower static portion adjacent to the upper static portion and a lower dynamic portion disposed below the lower static portion and adjustable by lower linear actuators that draw the lower dynamic portion toward the lower static portion to arc the lower flexmat outward.

A vehicle seating assembly includes a seat carrier defining a central opening. A seatback is pivotally coupled to the seat carrier. A seat flexmat is disposed in the central opening and operable between flexed and unflexed conditions. The vehicle seating assembly also includes a first thigh extension that is extendable and rotatable relative to the seat carrier and a second thigh extension that is extendable and rotatable relative to the seat carrier. The first thigh extension includes a first thigh flexmat operable between flexed and unflexed conditions. The second thigh extension includes a second thigh flexmat operable between flexed and unflexed conditions.
