In a seat device for a vehicle, a dynamic damper comprises a damper case that is formed from first and second case halves joined together so as to be capable of separating from each other to define a damper chamber therebetween, a weight that is housed in the damper chamber, and an elastic member that is disposed between the weight and an inner face of the damper chamber so as to allow vibration of the weight, the damper case being provided with a mounting part that is mounted on a frame of the seat. Thus, it is possible to provide a seat device for a vehicle in which replacement of a weight and an elastic member in order to adjust or change the damping characteristics is possible, and the ease of mounting a damper case on a seat is good.

The vehicle seat includes: an adjustment position selecting means for selecting an adjustment position of each part of the seat corresponding to the build of the occupant; a seat position adjusting means for the occupant to manually adjust a position of each part of the seat; and a seat position detecting means for detecting a position of each part of the seat. Build information selected with the adjustment position selecting means and positional information detected with the seat position detecting means are transmitted to an electronic control unit provided in the vehicle by wireless communication or wired communication. In the electronic control unit, proper positional information of each part of the seat estimated based on the build information and the positional information are checked against each other. When both pieces of information agree with each other, the occupant is notified of the agreement through a notifying means.

A vehicle seat strap retaining assembly having a seat cushion section, a seatback section and a strap attachment structure. The seatback section is attached to the seat cushion. The seatback section has a passenger's back supporting surface and an upper end surface that includes a central indentation area configured to receive a child seat retaining strap. The strap attachment structure is rigidly fixed to one of the seat cushion section and the seatback section beneath the central indentation area. The central indentation area and the strap attachment structure are positioned and configured such that with a child seat positioned on the seat cushion section, a securing strap of the child seat extending over the upper end surface of the seatback section overlays the central indentation area and attaches to the child seat supporting strap attachment structure.

A vehicle seat strap retaining assembly includes a seat cushion section, a seatback section, a strap retaining clip and a strap attachment structure. The seatback section is attached to the seat cushion, the seatback section having a passenger's back supporting surface and an upper end surface. The strap retaining clip is attached to a rear surface of the seatback section. The strap attachment structure is rigidly fixed to one of the seat cushion section and the seatback section beneath the upper end surface. The strap retaining clip and the strap attachment structure are positioned and configured such that with a child seat positioned on the seat cushion section, a securing strap of the child seat extending over the upper end surface of the seatback section passes through the strap retaining clip and attaches to the strap attachment structure.

Described are lightweight headrests with a perimeter frame 200 with an open central region. The open central region is spanned by a suspension membrane 100 held in tension. The suspension membrane provides support and cushioning functions to a passenger head without the need for internal structures or compression cushions. The perimeter frame of the headrest may have additional cross members spanning the rear portion of the headrest. These cross members may provide additional structure or locate attachment points for the headrest onto the seat.

In accordance with at least one embodiment, an adjustable head and neck system comprises a locking upright brace and a forehead support. The forehead support is coupled to the locking upright brace. The forehead support is configurable to support a user's forehead.

A transcranial neurostimulation system for a vehicle, the transcranial neurostimulation system comprising at least one electrode formed into an article of vehicle furniture such as a headrest of a seat.

The present invention relates to a headrest for a vehicle, the headrest comprising: a fixed elevating unit installed at the top end of a seat backrest and capable of being raised; a fixing shaft fixed to the fixed elevating unit and extending in a horizontal direction; a moving frame installed on the fixing shaft and including a guide rail and an automatic power transfer unit, so as to move linearly forward and backward and rotate upward and downward; a coupling main body coupled in a state enclosing the moving frame, and moving together with the moving frame; and a manually operated unit enabling the moving frame to be manually adjusted on the coupling main body. The manually operated unit is characterized by including an operating switch for electrical control so as to be capable of controlling a current flowing to the automatic power transfer unit.

An improved head restraint is provided for a reversible seat that is movable between two use positions, namely a forward-facing position and a rearward-facing position. The improved head restraint automatically pivots to a fold flat position upon unlocking of the seat, wherein the head restraint is positioned in this fold flat position during reversing seat movement, so as to reduce the seat height and clear the vehicle headliner. The head restraint is cable driven and operably connected to the seat linkages that control movement of the seat cushion and seat back during reversing movement. As such, the seat movement articulates the head restraint so that the head restraint angles forwardly toward the occupant in the forward-facing position and rearwardly toward the occupant in the rearward-facing position, while permitting the head restraint to automatically articulate to the fold flat position during travel of the seat between these two use positions.

A seat back frame assembly may include first and second brackets coupled with and extending outwardly from the seat back frame assembly. The first and second brackets may define first and second recesses, respectively. A cushion assembly may include first and second sides. The first and second sides may be disposed within the first and second recesses, respectively. An upper hood comprising first and second ends may be coupled with first and second brackets, respectively.
