A headrest apparatus in accordance with this disclosure supports the head and cervical spine during driving and driving events. The headrest apparatus including a headrest, one or more rods extending from the headrest, and a rotation mechanism located in the headrest coupled between the headrest and the plurality of rods. The headrest may include at least a front face, a rear face opposite the front face, a bottom face located between a lower portion of the front face and a lower portion of the rear face, and two side faces located opposite each other between the front face and the rear face. In a first position a profile of the front face may conform to a normal cervical spine curvature of an occupant in a seated position.

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 method for manufacturing a vehicle seat backrest comprises the steps of: providing first and second uprights of a backrest frame and a support member of an upper backrest adjustment device; positioning the first upright partly facing a first side face of the support member and the second upright partly facing a second side face of the support member; moving the first upright relative to the second upright along a transverse direction of the support member, in order to sandwich the support member such that the support member of the upper backrest adjustment device is mounted on the first and second uprights of the backrest frame so as to pivot about a transverse axis.

A seating assembly for a vehicle comprises: a seatback; an airbag having a stowed position and an inflated position, the airbag being configured to inflate from the stowed position to the inflated position in response to the vehicle impacting an object; a head restraint coupled to the seatback, the head restraint including a forward position, a rearward position, and a locking mechanism preventing the head restraint from moving from the forward position to the rearward position after taking the forward position; and as the airbag inflates from the stowed position to the inflated position, the airbag forces the head restraint from the rearward position to the forward position. As the airbag inflates from the stowed position to the inflated position and forces the head restraint to the forward position, the airbag does not contact the one or more support bars and does not force the seatback to change 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.
