摘要： A steering column assembly includes a column jacket provided with upper and lower jacket tubes telescopically coupled with each other for supporting therein a steering shaft rotatably. The column jacket is mounted tiltably on a vehicle body by upper and lower clamps and received between sidewalls of the upper clamp through distance brackets. One of the distance brackets includes lock protrusions that face the outer surface of the upper jacket tube, while the other includes support protrusions that face the outer surface of the lower jacket tube. When an operation lever is set to a lock position, the sidewalls is caused to press the distance brackets against the column jacket with the lock protrusions pushed on the upper jacket tube and the support protrusions pushed on the lower jacket tube. In this state, the column jacket is prevented from tilting and telescoping.

摘要： A seat sliding device consisting essentially of an upper rail fixedly mounted on a seat, a lower rail which is fixedly mounted on a vehicle body and has a substantially identical cross section with that of the upper rail, and a rolling member for assisting said upper rail in sliding along said lower rail. Each upper and lower rail has a substantially flat base portion to be mounted on said seat, a pair of side wall portions provided on both side ends of said base portion and which extend at right angles from said base portion, and a pair of flange portions provided on the each end of said pair of side wall portions and which extend at approximate right angles from said side wall portions. Further, the upper and lower rails engaged with each other, thereby forming a seat sliding body which have a unitary cross section in which a longitudinal length and a horizontal length thereof are identical.

摘要： An impact absorbing structure for vehicle steering systems includes a support and release mechanism for a tilt rotation center which mechanism makes it easy to change an impact load bearing capacity in a head-on collision. A steering column and a steering shaft are coaxially coupled to each other and are longitudinally rigid against compression. The steering column is supported by an upper bracket which can be released from a vehicle body in response to an impact and by a lower bracket which defines a tilt rotation center. A notch which has an open side to the front of the vehicle is formed in the lower bracket. A pivot, which is rigidly coupled to the steering shaft and provides a center of the tilt rotation, is engaged with the notch including a protrusion near the closed end.

摘要： A steering apparatus for a vehicle has: a steering shaft rotatable with a steering force applied from a steering wheel; a cable unit for transmitting a rotational force with an output member and a pair of cable wires; and a speed reducing gear disposed between the steering shaft and the cable unit. The output member makes a rotation in such a manner that the pair of the cable wires are pulled relative to each other. The rotational force is transmitted from the steering shaft to a side having a tire-and-wheel.

摘要： A steering apparatus (1) for vehicles capable of undergoing at least telescopic movement is proposed which enables substantial weight and cost reduction through shortening of the overlap (L′) of a movable jacket (7) with a base jacket (6) without affecting the high support rigidity of the movable jacket; also ricketiness of the movable jacket is removed; the movable jacket is engaged with the base jacket in a manner such that the movable jacket can freely slide, and a first lock assembly (20) locks the telescopic movement in synchronism with a second lock assembly (40) when an operation lever (27) is shifted and these lock assemblies unlock the telescopic movement in synchronism too.
