  • Publication number: 20130205912
    Abstract: A method of bending a long member includes applying a tensile force to the long member to draw out the long member in a lengthwise direction thereof, measuring a displacement of the long member after commencement of the application of the initial tensile force, and bending the long member by applying a correction tensile force and a bending pressure for bending the long member into a curved shape in the lengthwise direction simultaneously to the long member upon the displacement exceeding a predetermined tensile fracture threshold value within a predetermined period of time or after a lapse of the predetermined period of time without the displacement exceeding the tensile fracture threshold value. The correction tensile force is smaller than the tensile force at the time the displacement exceeds the tensile fracture threshold value or the tensile force at the lapse of the predetermined period of time.

  • Publication number: 20130206950
    Abstract: A slide rail device for a vehicle includes a lower rail; an upper rail supported on the lower rail to be slidably movable relative thereto; a lock mechanism between the upper and lower rails; a lock-operation lever inserted into the upper rail; a rotational supporter supporting the lock-operation lever to be rotatable between locked and unlocked positions; a handle; a biasing spring having an engaging portion which engages with the lock-engaging portion so that the engaging portion is immovable relative to the lock-engaging portion wherein the biasing spring supports the rear-end portion of the handle; and a spring support portion, provided on the upper rail, which is positioned immediately below the biasing spring and prevents the biasing spring from falling downward from an underside opening of the lock-operation lever when the rotational supporter supports the lock-operation lever.

  • Publication number: 20130186217
    Abstract: A power seat sliding apparatus does not produce an unusual sound and a good operation feeling is obtained. The power seat sliding apparatus includes a first load transmission member fixedly attached to an upper rail and having a first surface that intersects with an axis of a threaded rod and a second surface that opposes the first surface with a space in between, and a second load transmission member installed in the space between the first surface and the second surface, fixedly attached to the threaded rod, and having a third surface on which to abut the first surface and a fourth surface on which to abut the second surface. The first surface and the second surface are concave curved surfaces and the third surface and the fourth surface are convex curved surfaces.

  • Publication number: 20130169021
    Abstract: The present invention achieves a locking member of a vehicle seat device, a vehicle seat device, and a seat placement body, in which the lateral movement amount of the seat when receiving lateral movement acceleration can be suppressed without reducing the length of the engaging portion of the striker. The solution is a locking member provided with a striker, and a movement restriction member which is fixed to at least one side piece so that positions in the leftward/rightward direction of at least one part of the movement restriction member are the same as those of the left and right curved corner portions, wherein the movement restriction member includes a side spacer which forms a gap in the leftward/rightward direction between the engaging portion and the lock mechanism, to which the engaging portion is engaged.

  • Publication number: 20130168524
    Abstract: The present invention achieves a slide rail device for a vehicle in which it is possible to smoothly eject out objects that have fallen into the lower rail by using the upper rail, even if slide-restriction lugs, for restricting the slide position of the upper rail with respect to the lower rail, are formed by being cut and raised, and in which it is possible to reduce deterioration in rigidity of the lower rail. The solution is a slide rail device including slide-restriction lugs formed on a lower edge of each downward-extending portion of the lower rail by being cut and raised, the slide-restriction lugs superposing the stopper lug of the upper rail in a forward/rearward direction when viewed from the front.

  • Publication number: 20130134281
    Abstract: A slide rail device includes forward/rearward-movement restricting grooves formed on an upper rail; lock portions which are movable in the forward and/or rearward direction relative to the upper rail, wherein the lock portions are lock-engaged with the lock grooves and the forward/rearward-movement restricting grooves when the lock release lever is positioned at the locked position, and the lock portions are released from the lock grooves when the lock release lever is positioned at the unlocked position; and restricting lugs formed on an upper rail, wherein the restricting lugs restrict the lock portions from moving forward or rearward from the forward/rearward-movement restricting grooves, to which the lock portions correspond, by the lock portions coming in contact with the restricting lugs when the lock release lever is positioned at the unlocked position.

  • Publication number: 20130113261
    Abstract: A reclining apparatus achieves enhanced ease of coming off of a pole from a ratchet plate and hence a better operational feeling. Of a plurality of external teeth of a pole, at least one external tooth from an end is formed in such a manner that a tooth thickness is lessened more toward a tooth tip in comparison with a tooth thickness of other external teeth. The external tooth having a lessened tooth thickness is cut in one of two tooth planes located on a side of the end. The cut tooth plane has an inclined surface parallel to a flat surface containing all tangential lines to a pitch circle of one of two tooth planes of an external tooth having a large tooth thickness and situated adjacent to the external tooth having a lessened tooth thickness located on a side of the external tooth having a lessened tooth thickness.

  • Publication number: 20130111816
    Abstract: A window regulator for a vehicle, includes a slider fixed to a slide windowpane which moves up and down in a vehicle door; a guide rail which is fixed to the door panel, extends in an up/down direction of the slide windowpane and supports the slider; a wire orientation changing member provided the guide rail; a drive wire which is wound around the wire orientation changing member, wherein the drive wire moves up and down with the slider; a drive drum which moves the drive wire up and down; and a slide contact portion which is provided on the guide rail, extends in the up/down direction and is greater in length than the slider in the up/down direction, wherein the slider slides on the slide contact portion when the slider moves up and down.
