A vehicle occupant protection device includes: an airbag main body that includes a front-rear chamber that is deployed to a seat front side through a side of a head of an occupant by a gas ejected from an inflator operated when a collision of a vehicle is detected or predicted, and a tip end chamber that is deployed inward in a seat width direction from an end portion of the front-rear chamber on the seat front side; and a headrest that includes a main body portion that supports the head of the occupant from a seat rear side, and a side portion that is provided on at least a side of the main body portion, that protrudes to the seat front side until a deployment of the front-rear chamber is completed, and that is interposed between the front-rear chamber and the head of the occupant.

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.

An adjustment mechanism for a headrest for a seat has a scissor lever. The adjustment mechanism has at least one first lever arm and at least one second lever arm. A compensating lever arm is arranged at at least one lever arm end of each lever arm. A free end of each compensating lever arm has an attachment structure for attaching the compensating lever arm to a body. A lever arm end opposite the compensating lever arm of each lever arm has an attachment structure for attaching the lever arm to a body. A headrest for a vehicle seat, which has a headrest body is also provided.

A vehicle may receive sensor data captured by a sensor, determine that the sensor data represents an object in the environment, and determine a collision probability associated with a predicted collision between the vehicle and the object. Based at least in part on the collision probability, a position of a headrest of the vehicle may be determined relative to a head of an occupant of the vehicle. The headrest may be adjusted in one or more directions prior to occurrence of the predicted collision to minimize injury to the occupant due to the collision.
