A vehicle seat is provided with a seat pad formed of a foam material defining a seating surface for supporting an occupant and a rear surface opposite the seating surface. A speaker cavity for receiving a speaker assembly is formed in the pad and extends from the rear surface toward the seating surface. At least one speaker retention bracket is disposed in the speaker cavity. The retention bracket is co-molded with the pad so at least a portion of the retention bracket is encapsulated in foam material to retain the bracket in the cavity, the retention bracket having at least one retention feature extending within the cavity to cooperate with the speaker assembly and retain the speaker assembly in the pad. The speaker retention bracket is configured to mount a speaker assembly within the cavity to allow acoustic radiation to be transmitted through the foam material to a seated occupant.

A headrest adjusting device for headrest adjustment with respect to a backrest may have a headrest mounting bracket and a slide device movable mounted on the headrest mounting bracket. The headrest mounting bracket may have a seat belt retainer movable mounted on the headrest mounting bracket. A seat structure for a vehicle seat may also have the headrest adjusting device.

A side facing seat includes a seat back element and a moveable seat base element disposed below the seat back element. The moveable seat base element is moveable at least between a stored position and a seating position. Movement of the moveable seat base element is controlled by an activation element that is configured to engage with a locking mechanism such that the locking mechanism is able to lock the moveable seat base element in the stored position or the seating position.

An apparatus for manufacturing a surface-layered part includes: a main support that supports a surface layer member to be placed under a base member; a pulling device arranged at a periphery of the main support, wherein the pulling device includes a pulling member that pulls an edge of the surface layer member outward with respect to the support member; a base member clamping device that fixedly clamps the surface layer member, having been pulled outward by the pulling member, against the main support via the base member placed over the surface layer member; and a relieving device that separates the pulling member from the edge of the surface layer member to allow the edge of the surface layer member to wrap around the edge of the base member by an elastic restoring force of the surface layer member, thereby integrating them.

An adjustable vehicle seat including a seat frame forming a seat back, the seat frame being configured to couple with an aerospace vehicle, and a seat pan coupled to the seat frame, where one or more of the seat frame and the seat pan is configured to couple the seat pan to the seat frame in one of a plurality of positions relative to the seat frame so that an eye position of a seat occupant relative to instrumentation within the aerospace vehicle is decoupled from a size of the seat occupant.

A kinetic structural component may have a flexible structure having at least one degree of freedom. The flexible structure can be moved between a compressed position and an expanded position or vice versa. The flexible structure may have at least one substructure which is configured, when said flexible structure is in the expanded position, to expand to form a curve or an arc and/or linearly.

A seating posture is stabilized for the shoulders of a passenger seated on a vehicle seat. A vehicle seat is provided with a seat back configured to support the seated person from the rear. A shoulder support portion of the seat back configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand when air is supplied. When the air cell expands, one end portion of the shoulder support portion on the outside in the width direction of the vehicle seat moves more forward than the other end portion of the shoulder support portion on the inside in the width direction.

A vehicle seat including: a seat body configured to seat an occupant; a pressing mechanism that is provided at the seat body and is switchable between a pressing state, in which the pressing mechanism presses against the pelvis of a seated occupant, and a non-pressing state, in which the pressing mechanism does not press against the pelvis of a seated occupant; and a control section configured to control the pressing mechanism, in a state in which an occupant is sitting on the seat body, so as to alternate repeatedly between the pressing state and the non-pressing state.
