A headrest assembly includes a headrest bun having an interior portion. A support armature includes a portion thereof disposed within the interior portion of the headrest bun. A support member includes a lattice matrix comprised of a plurality of interconnected links. The support member is supported within the interior portion of the headrest bun by the support armature. A receptacle is operably coupled to the lattice matrix of the support member within the interior portion of the headrest bun and includes an interior cavity. A weighted insert is removeably received within the interior cavity of the receptacle.

A headrest assembly includes a lattice matrix having a plurality of three-dimensional (3D) cells. Each 3D cell of includes a node and a plurality of links outwardly extending from the node. The lattice matrix includes a plurality of sections including a first section having a first overall elastic modulus, a second section positioned adjacent to the first section and having a second overall elastic modulus that is higher than the first overall elastic modulus of the first section, and a third section positioned adjacent to the second section and having a third overall elastic modulus that is higher than the second overall elastic modulus of the second section. The lattice matrix is integrally constructed using an additive manufacturing technique, wherein the 3D cells of each section are provided in various patterns and cured to varying degrees to provide the varying overall elastic moduli of each section of the lattice matrix.

A ventilated adjustable headrest may include an adjustable metal insert, a nozzle fixedly attached to the adjustable metal insert. The nozzle may be in fluid communication with a perforated covering and one or more cushion elements. The nozzle may be telescopically coupled to one or more ventilation ducts. The one or more ventilation ducts may be configured to receive forced air from a ventilation system at an air inlet, and may be configured to deliver the forced air to the nozzle.

A reduced-impact-and-recoil headrest that includes a ratchet mechanism, allowing components to incrementally translate with respect to each other. The reduced-impact-and-recoil headrest includes an exterior housing surface that is deformable, providing cushioning for a vehicle occupant's head. The headrest also includes an interior compartment within the housing, with the ratchet mechanism disposed within the interior compartment. The headrest is configured to decrease the force of a collision experienced by the occupant, thereby decreasing the likelihood and severity of traumatic brain injuries resulting from the occupant's head striking a stationary headrest. Instead, the reduced-impact-and-recoil headrest is configured to incrementally move with the occupant's head, providing an incremental cushion for the occupant's head. The ratchet mechanism also prevents the reduced-impact-and-recoil headrest from automatically translating back to its pre-impact position, thereby decreasing the occupant's risk of ligament tear and whiplash.

A backrest for a vehicle seat, comprising a backrest frame on which a backrest head support element provided for supporting a seat user in the shoulder region can be pivoted. In particular, the support element can be pivoted via a drive unit arranged on the support element and a lever mechanism which interacts with the drive unit so as to be actuated by an external force.
