  • Patent number: 10436414
    Abstract: In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.

  • Patent number: 10434978
    Abstract: A webbing take-up device includes a spool that takes up a webbing worn by an occupant, and that is rotated in a pull-out direction due to the webbing being pulled out, and a lock base that limits pull-out direction rotation of the spool in a vehicle emergency. The webbing take-up device further includes an energy absorbing wire that undergoes deformation so as to permit pull-out direction rotation of the spool at or above a force limiter load when the lock base has limited pull-out direction rotation of the spool, and a second force limiter mechanism that adjusts the pressing force of the energy absorbing wire according to a remaining take-up amount of the webbing on the spool.

  • Patent number: 10428932
    Abstract: At a shift lever device, a shift lever is supported at a retainer due to the shift lever being inserted into the retainer from an upper side portion, and select shafts of the shift lever being inserted into select frames of the retainer. Here, at the select shafts, amounts of projection of circular shafts and intermediate shafts are small as compared with amounts of projection of plate shafts. At a time when the select shafts are inserted into the select frames, the circular shafts and intermediate shafts can pass supporting pillars of the select frames, and an angle of tilting of the shift lever with respect to the retainer in a left-right direction can be made to be small. Therefore, a left-right direction dimension of the retainer can be made to be small, and the shift lever device can be made to be compact in the left-right direction.

  • Publication number: 20190291635
    Abstract: A bracket is rotatable between a neutral position and a direction indication position in response to an operation by a user. A ratchet is slidable between an entry position where the ratchet enters a rotating trajectory of a cancel cam mounted on a steering shaft of a vehicle and a retract position where the ratchet retracts from the rotating trajectory interlocking with rotation of the bracket. A cam surface forming protrusion is provided on the bracket, and includes a cam surface including a neutral holding portion that holds the ratchet at the retract position when the bracket is at the neutral position. A cam surface forming wall is fixed so as not to be interlocked with rotation of the bracket, and includes a cam surface including a portion that allows the ratchet to enter to the rotating trajectory when the bracket is rotated to the direction indication position.

  • Publication number: 20190283707
    Abstract: A lock device includes a locking member, a movable member, and a transmission mechanism. The locking member is moved between a lock position at which it locks a locking subject and an unlock position at which it unlocks the locking subject. The transmission mechanism transmits a drive force to the movable member and moves the movable member. A movement state of the movable member is shifted between a relative movement state in which it is moved relative to the locking member and an integral movement state in which it is moved together with the locking member to move the locking member toward the lock or unlock position. The lock device further includes a detector of which an output value varies in accordance with movement of the movable member or the transmission mechanism, and a controller that performs a failure determination based on a change in the output value.

  • Patent number: 10399538
    Abstract: In a buckle device, a pressing force, applied from wire ropes to an inside wall face of a wire guide groove of a wire guide, is along an imaginary line passing through a center of a cover plate first hole portion of a cover plate fixing tab of a cover plate and a center of a wire guide hole portion of the wire guide as viewed from the vehicle inside, similarly to a pressing force applied to a first fixing bolt that fixes the cover plate to a support plate, and these pressing forces are both oriented in the same direction. This enables rotation moment to be suppressed from occurring at the cover plate when the wire ropes are pulled toward their length direction leading end side.

  • Patent number: 10378647
    Abstract: A shift lever device includes: a lever main-body; a hollow knob provided at a lever main-body distal end portion; a shift-button rotatably mounted to the knob; and a rod that is inserted-through interior of the lever main-body. The shift-button has a contact surface extending in direction of being away from a rotating-shaft of the shift-button, and that, when the shift-button rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod. Given that direction orthogonal to axial-direction of the rotating-shaft on plane orthogonal to axis of the rod is reference-direction, and that, among tangent-lines at contact points of the contact surface and the rod, tangent-line on plane orthogonal to the rotating-shaft is reference tangent-line, rotation range of the shift-button is set such that, partway through rotation, the reference tangent-line passes position at which the reference tangent-line becomes parallel to the reference-direction.
