An apparatus performs a method for estimating residual stress of a material such as plastics. The apparatus includes an inspection unit configured to emit a terahertz wave to a subject to be inspected and to detect the terahertz wave transmitted through or reflected from the subject, and a controller configured to estimate residual stress of the subject based on the terahertz wave detected by the inspection unit.

Residual stress estimation apparatus and method

A vehicle seat may include a protrusion member installed to a lower portion of a back frame inside a seatback to protrude forward and to absorb an impact on the hips of an occupant upon a vehicle collision, wherein a lower portion of the seatback, which has a protrusion shape due to the protrusion member, induces a sitting posture of the occupant to be modified when the occupant sits down on the vehicle seat, thereby reducing a gap between a head of the occupant and a headrest in a state that the hips of the occupant moves forward.

A seat back frame includes a guide pin and a lower end of the seat back frame is mounted to the rear end of the seat cushion frame to slide while rotating, and an upper end of the seat back frame is rotatably connected to a vehicle body. A guide bracket is fixedly mounted to the vehicle body, with the guide pin of the seat back frame being connected to the guide bracket to allow the guide pin to slide.

Apparatus for reclining rear seat for vehicle

A seat cushion extension apparatus comprises a slide rail disposed on a lower side of a cushion frame; an extension panel coupled to a front end of the slide rail and disposed on a front side of the cushion frame; an extension motor having a lead screw, disposed on the lower side of the cushion frame; a first hinge bracket coupled to the end of the slide rail and disposed at a rear upper side of the extension panel; and a second hinge bracket coupled to the end of the lead screw and disposed at a rear lower side of the extension panel, wherein the extension panel is configured to slide forward along the slide rail and to extend forward while rotating in a front upper direction through actuation of the lead screw driven by the extension motor.

Seat cushion extension apparatus

A reclining apparatus for a rear seat in a car may include a plurality of links provided on both sides of a cushion frame and each being rotatably coupled at both sides to the cushion frame or a car floor, and a locking module configured to couple a back frame hinge-connected to the cushion frame with a car body and slidably and rotatably connected with the back frame so as to allow the back frame to tilt at a variable angle in response to movement of the cushion frame by the rotation of the links.

Reclining apparatus for rear seat in a car

The present invention relates to a reclining apparatus for a head rest of a rear seat that includes: a reclining motor operably coupled to an integral lead screw; a carrier thread fastened to the integral lead screw; and a link module configured to transmit operation force from the carrier to a head rest module, wherein the head rest module angle is adjusted in a forward/rearward direction by the operation force from the carrier and the link module.

Reclining apparatus of headrest for rear seat in vehicle

The present invention relates to a reclining apparatus for a rear seat of a vehicle, having a back frame having a upper end and a lower end; a cushion frame having a front side and a back side, wherein the back side of the cushion frame is pivotally connected to the lower end of the back frame; a back frame locking module disposed on the upper end of the back frame, the back frame locking module removably engageable to a body panel and acting as a pivot center when engaged with the body panel; and a guide module configured to guide the cushion frame pivotally connected to the back frame so that the lower portion of the back frame pivots about the upper portion when the cushion frame slides up forward or down rearward to allow the back frame to move between an upright position and a reclined position.

Reclining apparatus for a rear seat of a vehicle

A seat for a vehicle constructed so that a side seat is provided on an opposite side of a center seat may include a first hinge shaft to which a center seat back of the center seat may be rotatably coupled for folding the center seat back forwards, a second hinge shaft to which a side seat back of the side seat may be rotatably coupled for folding the side seat back forwards, and a folding actuator assembly selectively engaging the side seat back with the center seat back, wherein the folding actuator assembly locks the center seat back to the side seat back when the side seat back may be folded, and releases the center seat back from the side seat back to fold only the center seat back when the center seat back may be folded.

Seat for vehicle

A back reclining apparatus interlocking with a seat cushion for a vehicle may include a back frame including a main frame fixed to a vehicle body and a reclining frame that may be selectively reclined around a reclining hinge on an inner surface of the main frame, a reclining locking unit connected to the main frame and the reclining frame to selectively release locking of the main frame and the reclining frame, a cushion locking unit selectively releasing locking of a cushion frame and the reclining frame, and a cushion sliding unit connected between the cushion frame and a floor panel to interlock with the reclining frame and to make the cushion frame move to slide forward when the locking of the reclining locking unit may be released and the reclining frame may be reclined around the reclining hinge.

Back reclining apparatus interlocking with seat cushion for vehicle

A fold-and-dive apparatus for a vehicle seat is provided, which includes a protrusion projecting from a seat back that is folded toward a seat cushion, a moving block moving on a connection link by the protrusion when the seat back is folded, a lock plate connected to the moving block by a cable to move upward and downward on the connection link so as to restrain and release the seat cushion, and an elastic member having both end portions installed in the seat cushion and a vehicle body, respectively, to make the seat cushion slide forward. Since the seat cushion slides forward when the seat back is folded, the overlap of bolster portions between the seat back and the seat cushion is minimized, and thus the evenness of the seat back that is folded toward the seat cushion and the luggage trim is maximally improved.

Fold-and-dive apparatus for vehicle seat

A fold-and-dive structure for a vehicle seat is provided, which includes a connection member connecting a cushion frame built in a seat cushion and a back frame built in a seat back to each other, a rotating link connecting a front end portion of the cushion frame and a support frame to each other, and a recliner provided on the support frame to which a lower end portion of the back frame is rotatably connected, wherein a guide frame is provided on a front side portion of the connection member, and the cushion frame is slidably coupled to the guide frame to make the seat cushion slide forward.

Fold-and dive structure for vehicle seat

An apparatus for preventing rotation of a seat frame for a vehicle having the seat frame that includes an inner link portion and an outer link portion that may be provided with a height adjustment device to adjust a height of a seat and a rack gear link may include a height link, wherein one end portion of the height link may be pivotally connected to a set bracket and the other end portion thereof may be pivotally connected to a cushion side member, and a rotation prevention link provided on the inner link portion wherein one end portion of the rotation prevention link may be pivotally hinged to the height link and the other end portion thereof may be movably installed on the set bracket.

Apparatus for preventing rotation of seat frame for vehicle

A fold-and-dive seat assembly for a vehicle is disclosed.
