    Abstract: A tubular body of a power transmission shaft made of fiber-reinforced plastic is provided with a cylindrical main body portion, and a second connection portion continuous with an end portion of the main body portion and to which a stab shaft is joined. The main body portion is formed with a weak portion which fails when a load input in the direction of an axial line exceeds a predetermined value. A linear rupture portion is formed on an outer peripheral surface of the weak portion. In the present configuration, cost reduction and weight reduction of the tubular body are made possible, and the tubular body fails infallibly when a predetermined load is input to the tubular body in the direction of the axial line.

  • Patent number: 10843721
    Abstract: A steering column may include an inner casing tube that rotatably mounts a steering shaft, an outer casing unit in which the inner casing tube is displaceable and fixable in an axial direction, and an energy absorption device operatively disposed between the casing tube and the casing unit. The energy absorption device absorbs at least some energy in a crash event when the casing tube is telescopically displaced relative to the casing unit. The energy absorption device may have at least two deformation strips fastened to the casing tube, and a deformation slide may be disposed on each strip. Each deformation slide may be connected to the casing unit and may encompass and jam external narrow sides of the respective deformation strip so that each deformation slide deforms the respective deformation strip when the deformation slide in a crash event is displaced in the axial direction on the deformation strip.

  • Patent number: 10676124
    Abstract: A steering column assembly comprises a telescopic shroud having an outer shroud portion and an inner shroud portion, a clamp rail fixed to the inner shroud portion including a slot that extends axially along the inner shroud portion, a clamp bolt that extends perpendicular to the shroud that may be rotated around its long axis by operation of a locking lever, and a toothed block that is connected to the clamp bolt having a row of teeth on each side, the pitch between teeth of each row being equal to, or a whole multiple of, the pitch of the teeth of a corresponding row of the slot. The toothed block is supported by a carrier that moves in response to rotation of the clamp bolt to in turn move the toothed block between a clamped position and an unclamped position and supports the toothed block such that the toothed block is free to move from side to side when in the slot.

  • Patent number: 10661821
    Abstract: A steering column assembly is provided that includes an inner shroud portion and an outer shroud portion, the inner shroud portion extending into the outer shroud portion and including a rail. The rail includes a slot with two opposing sides, each of which has teeth. A toothed block is provided that engages with the teeth of the slot, when a clamping mechanism is actuated. The toothed block is supported by a carrier that allows the toothed block to be free to move from side-to-side when engaged with the slot, and the teeth of the slot and the toothed block are shaped such that the toothed block may engage the teeth of the slot at any position when the clamping mechanism is actuated. The teeth of a first side of the slot prevent the block from moving in a collapse direction of the assembly and the teeth of the second side of the slot permit movement in a collapse direction but apply a thrust towards the teeth of the first side.

  • Patent number: 10633014
    Abstract: A locking device for a steering column may include an activating lever attached to a clamping bolt, which lever interacts with a pressure plate such that when the activating lever is rotated about an axis of the clamping bolt in a closing direction the steering column is clamped in the locking device, and such that when the activating lever is rotated in the opening direction the steering column can be adjusted. An abutment finger may be radially spaced apart from the clamping bolt and project in a direction of the axis of the clamping bolt. The abutment finger may engage in a window-like slot of the activating lever so that rotation of the activating lever is possible but limited in the opening and closing directions by abutment of the abutment finger against opposite abutment surfaces of the window-like slot, at least one which may comprise a damping cover.
