A bearing including an annular substrate defining a first and a second opposite axial ends; and a plurality of sliding components attached to and extending radially from the annular substrate, each sliding component extending at least partially between the first and second opposite axial ends of the annular substrate. A head restraint assembly including a head restraint having a body and a first and second post extending from the body; a first guide sleeve having a first bearing for receiving the first post; and a second guide sleeve having a second bearing for receiving the second post.

A headrest adjusting bracket surrounds posts from the headrest. A screw displaces one side of the bracket to apply a frictional force to the headrest posts. Protrusions on the interior surface of the bracket, proximal to each post, increases the surface area contact between the bracket and the posts when the screw is tightened.

A vehicle seat includes a seat back frame. The vehicle seat includes a suspension mat disposed within the seat back frame. The vehicle seat includes a linking member that elastically supports the suspension mat at the seat back frame. The vehicle seat includes a bushing that is disposed at an upper portion of the seat back frame. The vehicle seat includes a hollow stay inserted into the bushing, the stay protruding upward from the upper portion of the seat back frame. The vehicle seat includes a headrest fixed at an upper end of the stay. An upper end of the linking member is inserted into the stay from a lower end of the stay that is inserted into the bushing.

The technology can be embodied in a headrest that includes an enclosure that includes one or more acoustic transducers. The headrest includes a bar for mounting on a backrest of the seat, such that the mounted headrest is movable with respect to the backrest to different positions over an adjustable range. The bar includes one or more wires each of which is coupled to an electrical contact at one end, and an acoustic transducer at an opposite end, the one or more wires disposed within a hollow interior portion of the bar. The bar also includes an opening for permitting an electrical connection to be established between an electrical connector coupled to an external source, and the electrical contact coupled to the one or more wires. The connection is maintained over the adjustable range of the headrest by a mechanical bias on either the electrical connector or the electrical contact.

A backrest of a vehicle seat comprises a backrest frame, at least one headrest attachment rod, and a backrest upholstery. The backrest upholstery comprises at least one rear central shell, fixed to a rear face of the backrest frame. The rear central shell comprises at least one hole traversed by the at least one headrest attachment rod.

A headrest sleeve for assembly to a bracket fixed to a stay for supporting a main body of a headrest. The headrest sleeve includes a sleeve body formed in a tubular shape, a collar-shaped flange extending from one end portion of the sleeve body and disposed so as to be capable of contacting the bracket, a bracket-fitting section extending from the flange toward an opposite side from the sleeve body and configured to be capable of being fitted into a fitting hole formed in the lower bracket, and an anchor clip provided at the bracket-fitting section and configured to undergo elastic deformation and elastic recovery during the fitting of the bracket-fitting section into the fitting hole so as to engage with the bracket from an opposite side from the flange.

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 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 vehicle seat trim assembly for concealing a vehicle seat frame is provided with at least two adjacent panels, which are oriented at angles relative to each other. At least one slot extends through the at least two adjacent panels. An interior lining is formed from a flexible nonwoven fabric material and sewn within the at least one slot. The interior lining includes a slot with a width smaller than the width of the at least one slot in the at least two adjacent panels to enclose the slot in the at least two adjacent panels and to deform to provide clearance for a head restraint post. An embroidered seam is sewn into the vehicle seat trim member around the at least one slot and sewn into the interior lining to attach the interior lining to the at least two adjacent panels.
