The load applied to a connecting member that connects a second horizontal shaft to a base member in a headrest for a vehicle is reduced. The headrest comprises a pillar member including a right and a left vertical shaft extending upward from an upper part of a seat back, a right and a left first horizontal shaft extending forward from upper ends of the respective vertical shafts, each first horizontal shaft including a curved section, and a second horizontal shaft extending laterally between front parts of the first horizontal shafts, a base member including a base vertical portion extending vertically ahead of the vertical shafts, a base upper portion extending rearward from an upper end of the base vertical portion, and a right and a left first hole formed in the base upper portion to have the respective curved sections or the respective vertical shafts passed therethrough, a connecting member pivotably connecting the base upper portion to the second horizontal shaft, and a pad supported by the base member.

An apparatus for rotating a headrest of a vehicle seat includes a headrest that is rotated forward to support a seat occupant's head upon reclining of a seatback. A seat occupant's head is comfortably supported by the headrest and a comfortable relaxation posture is implemented.

Described is a sleeve device having a sleeve body for insertion into a vehicle frame of a vehicle seat. The sleeve body includes a tubular wall with an inner axial passage configured to receive a rod of a headrest and at least one elastomeric element overmolded to an outer surface of the sleeve device. The elastomeric elements may be provided in the form of ribs, rings, or other shapes. Additionally or alternatively, the sleeve device includes a latching mechanism having one or more flexible tabs configured to limit lateral and/or vertical movement.

The present disclosure relates to a seat element, in particular, a headrest for a vehicle seat, the seat element comprising at least one support bar made of metal, a first layer provided at an exterior surface of the support bar, and a cushion made of an upholstery material. Hereby, the first layer is formed by blowing on first fibers made of plastics which are thermally welded directly or indirectly to the exterior surface.

At least part of the first fibers extends away from the exterior surface and/or the first layer towards the outside into the upholstery material and is thermally cross-linked with the upholstery material, in particular, blown-on further fibers.

The present invention discloses a seat misuse alarm device (100). The seat misuse alarm device (100) includes a base (1), a seat (2), an alarm mechanism (3), and a switch triggering device (4). The seat (2) has a forward facing position and a rearward facing position relative the base (1). The alarm mechanism (3) has a switch (31). The switch triggering device (4) triggers the switch (31) to close for making the alarm mechanism (3) send out an alarm when the seat (2) is located at the forward facing position relative to the base (1).

A vehicle seat with a speaker-equipped headrest is provided, which is of a relatively simple structure to enable the speaker-equipped headrest to be easily mounted to/dismounted from a seat body after vehicle installation, and also provide increased versatility for installation in vehicles of various vehicle size classes. The vehicle seat with the speaker-equipped headrest includes: a male coupler that is connected to a speaker harness and fitted to a distal end of a headrest stay; and a female coupler that is connected to a main harness on a seat body side, and fitted to a headrest guide bracket supporting a headrest guide. Insertion of the headrest stay into the headrest guide allows the speaker-equipped headrest to be mounted to the seat body, and allows the male coupler and the female coupler to be fitted together to provide a connection between the speaker harness and the main harness.

A headrest support and a seat headrest in which the headrest support has a U shape and is configured for supporting a headrest. The headrest support includes an inner tube and an outer tube. The outer tube covers at least two end portions of the inner tube. The outer tube is secured to the inner tube by laser brazing.
