Abstract: A vehicle headrest including: a main portion including a central part of a front surface of the headrest; a side portion including a side part of the front surface of the headrest, the side portion including a lower side portion and an upper side portion which are divided from each other in a height direction; a first hinge shaft coupling the side portion to the main portion in a state where the side portion is capable of protruding forward to a side support position by being rotated around an axis which extends in the height direction and is inclined downward and inward in a width direction; and a second hinge shaft coupling the lower side portion to the upper side portion in a state where the lower side portion is capable of being raised forward around an axis extending in the width direction.

Abstract: A semiconductor device includes an RF circuit and a microcontroller. The RF circuit has: a transmission unit generating a transmission signal; a reception unit generating a first generation signal and a second generation signal; and a transmission/reception loop-back switching unit switching between a first coupling state of coupling an output terminal of the transmission unit to a transmission antenna and coupling an input terminal of the reception unit to a reception antenna and a second coupling state of coupling an output terminal of the transmission unit to the input terminal of the reception unit. The microcontroller switches the transmission/reception loop-back switching unit to the second coupling state and executes a test of the RF circuit on the basis of the second generation signal when the transmission/reception loop-back switching unit is in the second coupling state and an output signal of a first sensor circuit.

Abstract: A seat configuration member and a vehicle seat employing the seat configuration member are provided that are capable of covering reclining mechanism components and maintaining a high quality external appearance of the vehicle seat, and are moreover capable of achieving a reduction in the number of components. A lower side coupling and fixing portion disposed on a seat width direction outer side of a seat back board that is made from resin is integrally formed with an attachment portion that is L-shaped in plain view. A side airbag device is attached to a horizontal wall portion of the attachment portion. A seatback pad and a cover are mounted to the seat back board configured as described above, and the seat back board is assembled to side frames of a seatback frame.

Abstract: A vehicle seat and a seat back board are obtained in which a seat cover can easily be anchored to a resin spring. In a seat back board, clips attached on a cover side are engaged with vertical clip engagement portions of the seat back board, thereby enabling the cover to be anchored to a back spring section of the seat back board. An anchoring operation of the cover to the back spring section can accordingly be made easier than in conventional anchoring structures employing for example hog rings. Moreover, since only pairs of openings are formed to the back spring section of the seat back board in order to provide the vertical clip engagement portions, any detriment to the moldability of the back spring section can be avoided.

Abstract: A vehicle seat is obtained that allows good assembly operation characteristics of a side airbag device to a side-frame of a seatback frame. In a vehicle seat, stud bolts and nuts that fasten and fix a side airbag device to a side-frame are covered by a frame attachment section of a resin seatback spring. However, the frame attachment section is formed with openings at positions facing the stud bolts and the nuts. During manufacture of the vehicle seat, it is accordingly possible to perform a fixing operation of the side airbag device to the side-frame through the openings even in cases where the resin seatback spring is assembled to a seatback frame before assembling the side airbag device to the side-frame.

Abstract: A vehicle seat includes a seat back frame that has a pair of side frames, and that forms a skeleton member of a seat back, a back board portion that is formed by a resin plate, and that is disposed at a back side of the seat back frame, and a back spring section that is at least partially formed of resin, and that is integral with the back board portion, and that spans between the pair of side frames so as to be directly supported, and that is formed so as to be able to flexurally deform in a load application direction due to load toward a seat back rear side being applied.

Abstract: In a seat backboard, a backboard section is formed with a size that enables it to pass through between left and right side frames of a seatback frame. Coupling fixing sections are also provided at the two seat width direction sides of the backboard section, the coupling fixing sections engaging with the front side of the side frames and supported by the side frames. The seat backboard can thereby be attached to the seatback frame from the seat front side, and the degrees of freedom for design can be increased. The seat backboard is also provided with a cover anchor section to which outer periphery anchor portions provided to a seat cover are anchored.

Abstract: A vehicle seat includes a seat back and a head rest. The seat back has an air blower that is capable of aspirating air, and a blower duct that is capable of introducing the aspirated air toward a blowhole formed in the seat back. The head rest has a head rest main body and a stay attached to the head rest main body. The stay is inserted into the seat back, so that the head rest main body is vertically movably attached to the seat back. The air blower is disposed on the seat back such that a rotation center thereof can be positioned above the level of a terminal end of the stay that is moved to a lowermost position.

Abstract: An air conditioning seat includes a seat pad having a seating portion and a side support portion, blowing means for blowing air to an air path formed at the seat pad, a seat cover covering the seat pad, and a net-like cushion member capable of permeating air in a thickness direction and in a plane direction. An air path is formed at the seating portion of the seat pad. A hanging groove in a groove-like shape is recessed and on a boundary line of the seating portion and the side support portion. The an air blow out port of the air path is covered by the net-like cushion member. A communicating path reaching the net-like cushion member of the side support portion from the air path of the seating portion is formed by passing a back side of the hanging member at inside of the hanging groove.
