A vehicle seat includes a seat bottom coupled to floor of a vehicle and a seat back coupled to the seat bottom to move relative to the seat bottom. The seat back includes a backrest and a backrest adjuster configured to move relative to the backrest to change a shape of the backrest.

A vehicle seat in accordance with the present disclosure includes a seat bottom and a seat back. The seat back is coupled to the seat bottom to move relative to the seat bottom. The seat bottom is coupled to a floor of a vehicle and configured to move relative to the seat back.

Described are adjustable seats having a lower portion of a back rest attached to a seat frame having an upper frame and a lower frame. A pivot axis is positioned at an upper end of the lower portion of the back rest, and an upper portion of the back rest is pivotally attached to the pivot axis. The location of the pivot axis is configured to be positioned below a person's shoulders when the person is seated in the adjustable seat. The upper portion of the back rest is also pivotally adjustable relative to the lower portion of the back rest. A seat pan having a front portion pivotally coupled to a rear portion can be attached to the upper frame. An actuation mechanism is configured to simultaneously control a vertical height of the upper frame and a rotational position of the front portion of the seat pan.

A damper includes a housing in which an opening is formed, a cap closing the opening of the housing, a movable member movably housed between the housing and the cap, and a gel-like attenuating medium filled in a movable area of the movable member inside the housing. The housing and the cap are physical objects, the attenuating medium is filled between the physical objects and the movable member, and the housing and the cap are formed by the same principal material.

A reclining mechanism of a seat is provided that includes a fixed flange, a mobile flange, and locking parts being placed on first guide seats of guide seats on a first side of the fixed flange to be slidable inwardly and outwardly between the guide protrusions. Each locking part includes a locking gear on an outer end and is configured to engage with the internal gear of the mobile flange when sliding outwardly, thereby inhibiting relative rotation between the mobile flange and the fixed flange. The reclining mechanism further includes a locking cam rotatably provided at a center of the fixed flange and sub-parts provided on second guide seats of the guide seats on the first side of the fixed flange to be slidable inwardly and outwardly between the guide protrusions, each of the sub-parts being divided into a first part and a second part by a slit.
