A head securing assembly for supporting a user's head while sleeping and sitting upright in a seat includes a pair of clamps that is each positionable on a top side of a backrest of a seat in a vehicle. Each of the clamps is positioned on opposite sides of a headrest post with respect to each other. A support is coupled to each of the clamps and the support is directed forwardly from the backrest of the seat. A pair of cushions is each slidably coupled to the support and each of the cushions can be positioned on opposite sides of a user's head when the user sits in the seat. In this way the user's head is inhibited from tipping to the left or to the right when the user is sleeping.

A headrest module for a motor vehicle seat includes a base component and a headrest mounted in the base component. The headrest is configured to be guided in a vehicle longitudinal direction so as to be extendable and retractable relative to the base component. The headrest further includes a fixing mechanism having a first fixing element with teeth and a second fixing element configured to be moved towards the first fixing element for engagement between adjacent teeth. Contact faces of the two fixing elements are configured such that an extension of the headrest is possible under the action of a force on the headrest in an extension direction. A movement of the headrest in a retraction direction is possible under action of a release mechanism of the headrest module configured to move the second fixing element out of the region between the teeth of the first fixing element.

A headrest position adjusting device for a vehicle, may include a first motor mounted to a seatback frame; a first link connected to the first motor to be rotatable to a predetermined first angle in a leftward-rightward direction; a second motor mounted to the first link; a second link connected to the second motor to be rotatable to a predetermined angle in an upward-downward direction; a third motor mounted to the second link; a third link connected to the third motor to be rotatable with respect to a rotation axis of the third motor; and a headrest frame connected to the third link and mounted in a headrest pad.

A vehicle seat includes a seatback having an upper portion. An adjustable headrest assembly is supported on the upper portion of the seatback. The adjustable headrest assembly has a headrest bun and an adjustment mechanism for adjusting the headrest bun between extended and retracted positions. A trim component is disposed on the upper portion of the seatback having a relief portion. The relief portion is configured to receive a portion of the adjustment mechanism as the headrest bun is driven towards the extended position. A flexible cover member is coupled to the trim component at the relief portion. The flexible cover member has a plate member operable between extend and retracted positions. The portion of the adjustment mechanism abuts an inner surface of the plate member to move the plate member towards the extended position as the headrest bun is driven towards the extended position.

A rear-center head restraint system for an automobile vehicle includes a rear seatback of an automobile vehicle. A head restraint assembly is mounted on the rear seatback and is moved between a stowed position and a deployed position. The head restraint assembly includes a forward head restraint portion displaced from the stowed position in an upward direction and in a forward direction with respect to the rear seatback. A rear head restraint portion is positioned rearward of the forward head restraint portion and is displaced in the upward direction as the forward head restraint portion displaces away from the stowed position. At least one headrest post is fixedly positioned within the rear seat back. A release mechanism connected to the at least one headrest post is operated to release the head restraint assembly from the stowed position.

A headrest assembly for use in an automobile that is pivotal in the fore-aft direction. The headrest assembly includes a housing formed of a front shell and a rear shell. An armature operatively couples the housing to a seatback of an automobile seat. A ratchet mechanism couples the housing to the armature and effectuates the pivotal movement. The ratchet mechanism includes a fixed ratchet member statically connected to the armature and that defines a plurality of fixed ratchet teeth. The ratchet mechanism also includes a moveable ratchet member pivotally connected to the housing and that defines a plurality of moveable ratchet teeth. The moveable ratchet member is biased in an engaged position wherein the fixed ratchet teeth and the moveable ratchet teeth are interlocked and hold the housing a varying pivot angles in the fore-aft direction with respect to the seatback.
