In a steering device according to an aspect of the present disclosure, a load absorbing mechanism includes a large diameter shaft portion provided in an EA block, a long hole provided in a housing and guiding the large diameter shaft portion at the time of a secondary collision, a guide plate projecting inside the long hole and having a resistance portion plastically deformed by the large diameter shaft portion at the time of the secondary collision, and an EA guide overlapping the guide plate when viewed in a front-rear direction, provided in the EA block to be slidable on the guide plate at the time of the secondary collision, and formed of a material having a friction coefficient smaller than that of the EA block.

An energy absorption device for a steering column for a motor vehicle includes an energy absorption element for absorbing energy by a relative movement between at least two components of the steering column in a crash situation, and at least one arresting element for arranging in a blocking position for blocking the relative movement.

The outer column 25 has a front-side small-diameter tubular portion 37 into which the inner column 24 is press fitted. The inner-circumferential surface of the front-side small-diameter tubular portion 37 and the outer-circumferential surface of the inner column 24 come in contact with an interference fit at only a plurality of contact locations separated in the circumferential direction. At least one location in the axial direction of the column-side bracket 26 is welded to the outer-circumferential surface of the front-side small-diameter tubular portion 37 at only two weld locations that are close in the circumferential direction.

A steering column device has an inner column; an outer column combined with the inner column and having a slit extending in the axial direction, the inner column and the outer column configuring a telescopic steering column; a release bracket arranged inside the slit of the outer column and supported by and fixed to the inner column; a support bracket joined to the release bracket so as to be able to detach due to an impact load that is applied to the inner column during a secondary collision; and a telescopic friction plate having a function to increase a holding force for holding the steering column with respect to a vehicle-body-side bracket and supported by the support bracket.

In a steering device according to an aspect of the present disclosure, a load absorbing mechanism includes a large diameter shaft portion provided in an EA block, a long hole provided in a housing and guiding the large diameter shaft portion at the time of a secondary collision, a guide plate projecting inside the long hole and having a resistance portion plastically deformed by the large diameter shaft portion at the time of the secondary collision, and an EA guide overlapping the guide plate when viewed in a front-rear direction, provided in the EA block to be slidable on the guide plate at the time of the secondary collision, and formed of a material having a friction coefficient smaller than that of the EA block.

A steering system includes an upper jacket, a lower jacket, a support, a lock mechanism, and a shock absorber. The support supports the lower jacket. The lock mechanism switches a restriction of a telescopic adjustment and a termination of the restriction. The upper jacket includes a protruding stopper configured to regulate a position of the upper jacket at one end of a telescopic stroke range. The lock mechanism includes an opening and closing portion configured to enter a path of the stopper while the restriction of the telescopic adjustment is terminated, and configured to open the path of the stopper while the telescopic adjustment is restricted.

A steering jacket includes a first jacket member and a second jacket member in this order from a side proximal to a steering wheel, and the first jacket member and the second jacket member overlap each other such that the steering jacket is extendable and retractable in an axial direction. An actuator is connected to an extension bracket that is attached to an outer surface of the first jacket member and extends toward the front of a vehicle body, so as to extend and retract the first jacket member with respect to the second jacket member.

A steering column assembly includes a lower jacket. The steering column assembly also includes an upper jacket in telescoping engagement with the lower jacket. The steering column assembly further includes an energy absorbing strap assembly operatively coupled to the upper jacket. The energy absorbing strap assembly includes a strap having a stationary leg and a moveable leg connected by a curved portion to form a substantially U-shape. The energy absorbing strap assembly also includes a metal pin extending through the stationary leg and the moveable leg.

A steering column having an adjustment limit stop device comprising a body receiving, in a deformable bearing, the sleeve carrying the steering wheel and a mechanism for clamping a shaft with a lever carrying a clamping device compressing the deformable bearing. The steering column comprises a stop device provided with a stop edge carried by the sleeve and with which a lock cooperates that limits the adjustment travel of the sleeve while being retracted after the adjustments of the column have been clamped, allowing the sleeve to travel, in the event of an impact on the steering wheel, in order to absorb the energy.

A collapse-limiting assembly for a steering system is provided. The collapse-limiting assembly comprises a housing and a moveable member. A pyrotechnic charge is located in the housing and, in response to an impact event, is caused to fire the moveable member into a discharged position and limit the amount of collapse of a steering column. The steering column includes at least two axially moveable portions that move axially relative to each other between an extended position and a retracted position. When the moveable member is fired into the discharged position, it is located in a travel path of at least one of the axially moveable portions.
