A pump-valve integrated machine for a pneumatic lumbar support of an automobile seat includes: an air pump; a pump valve connection base that is provided with a one-way air outlet structure, which is opposite to and in communication with an air outlet hole of the air pump; an electromagnetic air valve lower base that is fixed onto the air pump and is provided with a mounting groove and a ventilation hole are; a normally open electromagnetic air valve that is disposed on the electromagnetic air valve lower base and has an air inlet end corresponds to the ventilation hole; an electromagnetic air valve upper cover that is provided above the normally open electromagnetic air valve and has an air outlet connector corresponds to a valve core of the normally open electromagnetic air valve; and a control circuit board.

A power seat operating device for a vehicle has a switch module for operating a power seat of the vehicle. In particular, the switch module includes a plurality of seesaw type switches to control operation directions of the power seat, and the operation directions of the power seat according to the operation of each switch is displayed with arrows on a display, thereby improving the switch operating convenience of the user such as accurately controlling the operation direction of the power seat according to the switch operation by the user, and accurately recognizing a selection state and an operation direction of the switch desired by the user.

A vehicle seat comprising: a seat cushion frame that structures a frame of a seat cushion and that is configured to support buttocks of a seated vehicle occupant; a seat cushion pad mounted to the seat cushion frame; and a pelvis supporting portion having a push-up portion that is provided at a seat lower side of the seat cushion pad along a seat left-right direction and that, by being displaced toward a seat upper side, pushes a seat rear side portion of the seat cushion pad toward the seat upper side.

A backrest having features that support proper sitting posture of a user to improve back health and posture may be utilized. The backrest may include a front wall with wings extending to the left and right and diagonally forward to reduce Kyphosis of a user when sitting against the backrest. A combination of the front wall and wings may causing the user's (i) back ribs to be raised and gently tilted forward and (ii) thoracic spine region to be gently thrusted forward. By thrusting the thoracic spine region and raising and tilting the back ribs, a user's abdominal cavity may be expanded, and thereby reinforcing the ideal positioning of the cervical spine so that the user's head naturally positions on axis and does not “dump” forward.

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 lumbar support device that can reduce a cost involved. One aspect of the present disclosure is a lumbar support device including a base, a pressure-receiving plate arranged at a seat-front side relative to the base, a hinge mechanism moving the pressure-receiving plate in seat front-rear directions, and a lead screw causing the hinge mechanism to be operable. The hinge mechanism includes a first paddle and a second paddle pivoting about a hinge pin in the seat front-rear directions. The first paddle includes a first pressing portion pressing the pressure-receiving plate toward the seat-front side and a first coupling portion coupled to a lead screw so as to be shifted in a seat-width direction as the lead screw rotates. The second paddle includes a second pressing portion pressing the pressure-receiving plate toward the seat-front side and a second coupling portion rotatably coupled to the based.

Proposed are a seat for a vehicle and a method of controlling the same capable of sensing whether an occupant is snoring and of changing the posture of the occupant so as to induce sound sleep of the occupant. The seat for a vehicle includes a seat cushion, a seatback, a side bolster, a headrest, a sensing device mounted in the headrest to sense whether an occupant is on the seat and whether the occupant is snoring, a posture-changing device mounted in at least one of the seat cushion, the seatback, the side bolster, or the headrest to change the posture of the occupant, and a controller configured to determine whether the occupant is on the seat and whether the occupant is snoring based on a sensing signal output from the sensing device and to operate the posture-changing device.

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.
