This invention relates to a headrest folding device having a simple locking and unlocking structure, wherein a locking bar of a lifting slider is disposed directly under a locking groove of an upper latch, and stably guiding vertical linear sliding of the lifting slider.

A headrest structure is provided and includes a body and two supporting rods. The body includes a covering cushion and an automated external defibrillator (AED). The AED is enclosed by the covering cushion. Each of the supporting rods includes a linking end and a combining end opposite to the linking end, and each of the supporting rods is connected to the body with the linking end so as to support the body. Based on this, the AED is assembled in the body to improve the applicability of the AED, so that patients experiencing cardiac arrest can be treated properly and instantly.

A vehicle seat control apparatus is equipped in a vehicle capable of travelling by automated driving and is configured to set a position and attitude of a seat of the vehicle to a driving position in low automated driving and to set the position and attitude of the seat to a relaxing position in high automated driving. The vehicle seat control apparatus includes an alertness detecting device configured to detect an alertness level of a driver seated on the seat, a computation control device configured to drive the seat driving device to perform an alerting operation if the alertness level is lower than a predetermined level when driving of the vehicle transitions from the high automated driving to the low automated driving, and a seat driving device configured to displace the seat at a higher speed than at a transition from the driving position to the relaxing position.

A passenger seat may be configured to adjust between an upright seating position and a lie-flat sleeping position (which may include one or more intermediate reclined seating positions) via independent rollers attached to the seat pan, or seat bottom, and to the backrest. As the passenger seat transitions between the upright seating position and the lie-flat sleeping position, guide channels set into the left and right frame rails direct the movement of the independent rollers through the guide channels and thereby control the angles of the seat pan and the backrest throughout the transition.

A headrest includes a stay having left and right legs; a headrest main body attached to the stay and able to rotate in a front-rear direction; a pair of elongated holes made in a bottom surface of the headrest main body and a pair of closing members arranged on the bottom surface of the headrest main body, covering the elongated holes, wherein each closing member includes a main plate and a sub-plate, the main plate has an insertion hole guiding one leg of the stay and moves in the front-rear direction as the main plate is rotated, and the sub-plate is provided, overlapping the main plate, and is able to move as the main plate moves; the main plate and the sub-plate may move as the headrest main body is rotated, while covering the elongated hole made in the bottom surface of the headrest main body.

A vehicle seat is provided including at least first and second movable seat elements relatively to each other and at least one actuator ensuring a relative movement between both elements. The actuator includes a sensor for measuring a piece of representative information of the position of a first seat element relatively to a second seat element. The sensor includes an inclinometer secured to the first seat element. The piece of representative information of the position of the first seat element is an inclination of the first seat element.

A seat for vehicles includes: a seat back frame; and a pressure receiving member that is mounted on the seat back frame to support a back of an occupant. The seat back frame includes a lower seat back frame and an upper seat back frame mounted on an upper portion of the lower seat back frame in a forwardly and rearwardly swingable manner, and the pressure receiving member is disposed from an area corresponding to the shoulder of an occupant to an area corresponding to the waist of the occupant and is supported by the upper seat back frame.

An active head restraint for a seating assembly of a motor vehicle comprises a structural support for a seatback of the seating assembly, a movable head restraint pad having a stowed position and a deployed position, and a linkage deployment mechanism. The linkage deployment mechanism comprises an upper and lower bar pivotally attached at a forward end to a rear surface of the movable head restraint pad and pivotally attached at a rearward end to an outer tube fixed to an upper portion of the structural support. An inner tube reciprocates within the outer tube. A trigger mechanism is operatively connected with a lower end of the inner tube and urges the inner linkage and an actuating link to a raised deployed position in response to a rear impact event. The actuating link applies an upward force to the lower bar to deploy the movable head restraint pad.

A pneumatically adjustable seat includes a seat frame having a seat back frame portion and a headrest coupled to the seat back frame portion. The headrest includes a resilient cushion. A drive assembly includes a contact member operatively associated with the resilient cushion. A first bladder is operatively coupled to the contact member and in fluid communication with a source of pressurized fluid. Inflation of the first bladder via the source of pressurized fluid extends the contact member from a first position nearer the seat back frame to a second position further from the seat back frame. A second bladder is operatively coupled to the contact member and in fluid communication with the source of pressurized fluid. Inflation of the second bladder via the source of pressurized fluid pivots the contact member away from an occupant of the seat.

A passenger protecting device including: an airbag device including an airbag that receives a supply of gas from an inflator and is inflated and expanded, by a front expanding portion that includes a front inflating portion to be inflated and expanded at a seat front side of the head portion and at least one of a chest portion and shoulder portions of the passenger, and a pair of left and right lateral expanding portions that include lateral inflating portions that are connected to the front expanding portion and are inflated and expanded at sides of the head portion of the passenger; and a position changing device that changes an inflated and expanded position of the airbag in a seat transverse direction, in accordance with a direction of collision of a collision body with respect to the vehicle seat.
