A method of assembling a vehicle seat is provided, comprising: providing a seat back frame; forwardly movably connecting a headrest for supporting a head of a seat occupant to the seat back frame; mounting a rear-end collision detector to the seat back frame at a position behind the seat occupant, operatively connecting the rear-end collision detector to the headrest; disposing a link member at a position lateral to the rear-end collision detector; forming a front extending portion that inwardly extends in a right-to-left direction at a front end of a lateral face of the side frame; and forming a rear extending portion that inwardly extends in the right-to-left direction; wherein a protruding portion is formed from a portion of the lateral face of the side frame that faces at least the part of the bracket, the link support shaft being disposed at a same height as the protruding portion.

A vehicle seat having an adaptable lateral support and method of adapting lateral support are provided. The seat has a seat frame on which a seat cushion and/or a backrest cushion and at least one actuator is retained, wherein the seat cushion and/or the backrest cushion has at least one laterally arranged, resiliently deformable side wall cushion for the lateral support of a person sitting on the vehicle seat and the actuator is operationally connected to the side wall cushion and configured to apply a deformation force for the resilient deformation of the side wall cushion. The vehicle seat has a cable element which connects the side wall cushion to the actuator in a force-transmitting manner so that the actuator introduces the deformation force by tensioning the cable element directly from the cable element into the side wall cushion to deform the side wall cushion to change the lateral support.

Provided is a lumbar support disposed in a vehicle seat and supporting the user's lumbar vertebra. According to the present invention, there may be provided a lumbar support for a vehicle seat that includes: a support panel configured to support the user's back; first and second wires configured to support a lower portion of the support panel; a tow wheel winding the first and second wires on a circumferential surface thereof with ends of the first and second wires fixed thereto; and an actuator configured to rotate the tow wheel, in which the tow wheel has: a first wire guide groove extending around the circumferential surface to wind the first wire; and a second wire guide groove extending around the circumferential surface at a different position from the first wire guide groove in a thickness direction to wind the second wire. The lumbar support for a vehicle seat according to the present invention can improve sitting comfort by appropriately changing a force that supports the lumbar vertebra.

A vehicle seating assembly includes a frame, a front closeout panel supported on the frame and an articulating flexmat assembly operably coupled with at least one of the front closeout panel and 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. The upper flexmat includes an upper cable coupled with the upper flexmat and an upper cable regulating motor operably coupled with the upper cable. The articulating flexmat assembly also includes a lower flexmat extending from the first side of the frame to the second side of the frame. The lower flexmat includes a lower cable coupled with the lower flexmat and a lower cable regulating motor operably coupled with the lower cable.

A lumbar support (100) for a seat (200) defining a back plane (E) comprises a support device (10) having an upper end (O) including an upper angle of inclination () with the back plane (E) and a lower end (U) including a lower angle of inclination () with the back plane (E) and forming an crown of the curvature (S) located in an adjustable position between the upper end (O) and the lower end (U). The lumbar support (100) further comprises at least one angle adjuster (20, 25) connected to the upper end (O) or the lower end (U) and adapted to vary the upper angle of inclination () or the lower angle of inclination () in order to adjust the position of the crown of the curvature (S), and an actuator (30, 35) for adjusting the angle adjuster (20, 25).

A seat backrest includes right and left side frame segments, a pressure receiving member disposed between the side frame segments movably in a front-back direction, and a cushion pad covering the front of the side frame segments and pressure receiving member. The pressure receiving member includes a main body part, and extending parts extending laterally from both sides of the main body part. The cushion pad includes a back receiving part covering the front of the main body part, and bank parts disposed on both sides of the back receiving part, protruding forward from both sides, and covering the front of the extending parts and side frame segments. A recess is formed at an area, facing a corresponding extending part of the extending parts, of a rear surface of each bank part.

A lumbar support apparatus for a vehicle seat includes: a seatback frame having an adjustable inclination angle; an operating mechanism disposed at an upper portion of the seatback frame, the operating mechanism including a connector generating an operating force in a vertical direction by being in contact with a fixture fixed to a vehicle body when the inclination angle of the seatback frame is adjusted; and a support mechanism disposed at a lower portion of the seatback frame, connected to the connector, receiving the operating force generated from the connecting mechanism, and configured to slide in a front and rear direction depending on an application direction of the operating force, such that when the inclination angle of the seatback frame is adjusted to be directed rearward, the support mechanism receives the operating force of the operating mechanism and is advanced forward to support a waist of an occupant.

The disclosure relates to a lumbar support assembly, wherein the inclination of a mat is controlled by upward and downward movement of a single nut, thereby making it possible to reducing weight and manufacturing cost of the assembly.

According to one embodiment of disclosed herein, a lumbar support assembly includes: a mat having opposite sides that are rotatably connected to opposite sides of a seat frame, respectively; a driving unit coupled to the mat, and including a nut that is configured to be moved upward and downward; and a tension unit having first and second sides that are respectively coupled to the first and second sides of the seat frame, and coupled to the nut while surrounding a rear portion of the mat, wherein the nut allows the mat to be moved frontward or rearward by pulling or loosening the tension unit according to direction of movement.
