A latch device includes a latch engageable with a rod portion of a striker, and is capable of transition to a locked state in which the latch is engaged with the rod portion and to an unlocked state in which the latch is disengaged from the rod portion, and includes a first shaft member that supports the latch in a manner that permits the latch to rotate, and a base member that supports the first shaft member. The base member is a unitary member which includes a first support wall disposed on one side of the latch and configured to support one end of the first shaft member, a second support wall disposed on an other side of the latch and configured to support an other end of the first shaft member, and a connecting wall that connects the first support wall and the second support wall.

A vehicle seat including a pivot bracket, a back frame, a linear adjustment mechanism, a striker, and a latch. The back frame is pivotally connected to the pivot bracket and configured to pivot about a pivot axis. The back frame includes a first end spaced apart from the and disposed below the pivot axis. The latch is configured to selectively attach the linear adjustment mechanism to the first end of the back frame so that as the first linear adjustment mechanism translates, the back frame pivots from a first use position and a second use position, and selectively detach the linear adjustment mechanism from the first end of the back frame so that the back frame is pivotable to a non-use position.

A backboard assembly for a vehicular rear seat is disclosed. The backboard assembly includes an upper part and a lower part, which are made of a hard plastic material. The backboard assembly prevents the formation of a gap between the lower part and a luggage board, regardless of the operational mode of the rear seat. When a seat back is folded, the upper part, the lower part, and the luggage board are aligned in a horizontal direction, thereby allowing the space for passengers in the rear seat to be completely integrated with a luggage compartment.

A back panel of a motor vehicle seat includes, on its visible external back side, a thermal layer.

A cushion support member 41 includes: a lower region 42 whose left-right full width is less than an interval between a pair of side frames 14 of a seat back frame 12; an upper region 45 located above the lower region 42 and having a left-right full width greater than the lower region 42. the upper region 45 is divided into a central region 46 including a central part in the left-right direction and provided with a predetermined left-right width, and outer regions 47 provided on outer sides with respect to the central region 46 in the left-right direction, and the central region 46 is arranged as a retracted region which is cut off to leave the outer regions 47 or is recessed to a side opposite to a cushion member with respect to the outer regions 47.

Provided is a conveyance seat having a good seating feeling and a suitable shock absorbing structure at the time of a rear collision. A conveyance seat has a configuration in which a cushion material is placed on a back frame and is covered with a skin material. The back frame includes right and left side frames which constitute side portions in a seat width direction and extend in an up to down direction. A surface of a cushion front portion disposed on a seat front side of the back frame in the cushion material is provided with a skin pull-in groove for pulling an end of the skin material and a surface groove disposed on the outside of the skin pull-in groove in the seat width direction and extending in the up to down direction. A back surface of the cushion front portion is provided with a back surface groove which is disposed between the skin pull-in groove and the surface groove in the seat width direction and extends in the up to down direction. The surface groove is disposed at a position overlapping the side frame in the front to back direction of the seat.

There is provided a conveyance seat that suppresses the deterioration of the sensitivity of a load sensor to an input load even when a heater wire and the load sensor are disposed to overlap each other. A conveyance seat includes a seat cushion that supports buttocks of an occupant; a seat back connected to the seat cushion to serve as a backrest for the occupant; a load sensor provided at the seat cushion or at a portion of the seat back; a heater wire disposed on an occupant side with respect to the load sensor; and an intermediate member that positions the heater wire. The intermediate member is disposed between the load sensor and the heater wire.

A seating assembly is provided that includes a seating assembly frame that includes a seatback frame, and a seat frame. The seating assembly further includes a seatback panel coupled to an upper portion of the seatback frame and movable between a stored position relative to the seatback frame and an extended position relative to the seatback frame, and an adjustment mechanism coupled to the seatback panel and the seating assembly frame and movable between a first position and a second position in response to an actuating force.

Provided is a conveyance seat in which a duct connected to a fan can be compactly disposed, and the fan is provided in a pan-frame-type seat cushion. The vehicle seat includes a seat cushion (S2) and a blower (48) provided in the seat cushion (S2). The seat cushion (S2) is provided with a plate-shaped pan frame (42). The blower (48) is provided below the pan frame (42), a duct (49) is connected to the blower (48), and an opening (42a) through which the duct (49) extends is formed in the pan frame (42).
