  • Patent number: 11046352
    Abstract: A steering column includes: a cylindrical member that holds a steering shaft in such a manner as to allow extension and contraction of the steering shaft; a holding member that holds the cylindrical member; a fixture member that is fixed to a vehicle body; a coupling member that couples the fixture member and the holding member; and an energy absorbing member that is partially fixed to the holding member. The coupling member uncouples the fixture member and the holding member when the holding member moves forward for a specified distance in an axial direction. The fixture member has an engaging section arranged at a position where the engaging section is engaged with an engaged section of the energy absorbing member when the holding member moves forward for the specified distance or longer in the axial direction.

  • Patent number: 10246119
    Abstract: A steering column device includes a cylindrical inner jacket; a cylindrical outer jacket in which the inner jacket is slidably inserted; and a steering shaft rotatably supported in the inner jacket and the outer jacket. The outer jacket is divided into a molded first half member and a molded second half member at a plane including an axis of the outer jacket. According to this steering column device, in molding the outer jacket, it is not necessary to set a draft for a core along the axial direction on the inner circumferential surface of the outer jacket.

  • Patent number: 10160475
    Abstract: In a steering column device, a locking shaft is disposed on a vehicle front side relative to an operating shaft for an operating lever in parallel to the operating shaft. On the locking shaft, a cam member is disposed which is configured to press a locking member against a locked member via a guiderail in such a direction as to engage the locking member with the locked member. On the other hand, on the operating shaft, a linking member is disposed which is configured to bring the cam member into a state where the locking member and the locked member are disengaged from each other when the operating shaft is moved to an unlock position.

  • Patent number: 9849906
    Abstract: A steering column device includes a coupling mechanism that couples an auxiliary restricting member with an inner column when a lock mechanism is in a locked position. In operation, when a load exceeding a set value is applied to the inner column in its cylinder-axis direction, the auxiliary restricting member moves together with the inner column and leaves its engagement with a restricting member, so that the restricting member departs from a restricting position where it can be engaged with the inner column.

  • Patent number: 9623896
    Abstract: In a steering column device, a small-diameter part of an operating shaft on one side of a step part on the operating shaft between a pair of clamp parts penetrates through an impact absorbing slot along a laminating direction. By operating an operating lever, the dimension of cam mechanism in the direction of the operating shaft is increased. Consequently, between the step part and an inner face of the other clamp part, a movable-side friction plate is brought into pressure contact with a stationary-side friction plate to be held. In this situation, when a load exceeding a set value is applied to the steering column device, the movable-side friction plate slides on the stationary-side friction plate to absorb the impact.

  • Patent number: 9376137
    Abstract: A steering device includes: a steering shaft and a column jacket that are telescopically adjustable in an axial direction; a lock plate provided with a plurality of holes; a lock mechanism that moves a tooth such that the tooth advances to the lock plate to be engaged with one of the holes, and retreats from the lock plate to be disengaged from the hole. The lock plate includes a bent portion as a stopper at an end portion of the lock plate in the axial direction, and the stopper restricts a movement of an upper jacket relative to a lower jacket in the axial direction by abutting on the lock mechanism in the axial direction when the steering shaft and the column jacket is telescopically adjusted.

  • Publication number: 20160176433
    Abstract: A movable teeth row formed member is supported so as not only to move together with an operation shaft in a position adjusting direction but also to rotate around a pivot shaft which is parallel to the operation shaft in a first rotating direction and a second rotating direction. A lock biasing mechanism causes the movable teeth row formed member in the first rotating direction via an elastic member as an operation lever is operated to rotate in a locking direction, so that a movable teeth row is caused to move towards a fixed teeth row for meshing engagement with the fixed teeth row.

  • Publication number: 20160159387
    Abstract: Provided is a steering device including a hollow upper jacket that accommodates a steering shaft, a first engagement member, a rotary shaft that extends in a direction intersecting an axial direction of the steering shaft, and a second engagement member that is a component independent from the rotary shaft. The first engagement member has an engagement hole and is attached to the upper jacket. The second engagement member has an engagement projection which is engageable with the engagement hole. The second engagement member is movable between a lock position where the engagement projection engages with the engagement hole and a release position where the engagement projection is disengaged from the engagement hole, in accordance with a rotation of the rotary shaft. A vertical direction of the second engagement member between the lock position and the release position is different from a rotating direction of the rotary shaft.
