摘要： A method for optimising an energy-absorbing strap includes the steps of: (1) producing a single metal sheet, including a first connecting portion, for connecting to one of a support bracket and a fixed part of a vehicle, and a second connecting portion, for connecting to the other of the support bracket and the fixed part of the vehicle; and (2) producing a weakening in the single metal sheet to separate the first connecting portion from a tearable portion; bending a portion of the single metal sheet to produce a bent portion that interconnects the second connecting portion and the tearable portion, the second portion being bent back around in relation to the tearable portion; wherein the steps are selected to produce a desired energy-absorbance profile.

摘要： A gearbox assembly includes a housing, an output shaft, a wheel gear, an input shaft, a torsion bar, an electric motor, a worm gear and a key lock. The wheel gear may be fixed to the output shaft for engagement with a wheel gear. The torsion bar may connect the input shaft to the output shaft. The worm gear may be rotationally fixed to the rotor and engages the wheel gear to transfer torque from the motor to the output shaft. The key lock may include an adapter, an annular outer part, a web, and a locking collar. The key lock may be fixed to the housing and is movable between an extended position in which a part of the key lock engages the locking collar and a retracted position in which the part is held clear of the locking collar.

摘要： A steering column assembly is disclosed that comprises: a housing having outer, intermediate and inner elongate, telescopically mounted housing portions movable relative to one another along an adjustment axis; a steering column rotatably mounted in the inner elongate housing portion and being configured at one end for attachment of a steering member (e.g. a steering wheel); a leadscrew rotatably mounted on the intermediate housing portion and having first and second threaded portions of opposite handedness; a motor for rotating the leadscrew; a first displacement member screw-threadedly mounted to the first threaded portion of the leadscrew and connected to one of the outer and inner elongate housing portions; and a second displacement member screw-threadedly mounted to the second threaded portion of the leadscrew and connected to the other of the outer and inner elongate housing portions; whereby rotation of the leadscrew causes displacement of the first and second displacement members in opposite directions along the adjustment axis.

摘要： A collapsible steering column assembly is disclosed, which comprises a collapsible steering column shroud that supports a collapsible steering shaft. The steering shaft has a first end for connection to a steering wheel of a vehicle a mounting bracket that supports the steering column shroud relative to the vehicle. The mounting bracket comprises a fixed portion secured to a fixed part of a vehicle body and a releasable portion secured to the steering shaft. The releasable portion is also secured to the fixed portion of the mounting bracket by one or more frangible connectors. The connectors are adapted to break in the event of a crash to permit the releasable portion and the steering shaft to move relative to the fixed portion. The fixed portion includes a first anvil which has a rounded nose that faces towards the steering wheel, and a guide part which is offset from the first anvil in a direction away from the steering wheel. The guide part has a surface that is vertically offset from an adjacent surface of the fixed portion of the mounting bracket to define a space bounded by the surface of the guide part. The adjacent surface of the fixed part of the mounting bracket defines a convoluted path. An energy absorption strap has a first region fixed to at least one of the steering column shroud and the releasable portion and from which the energy absorption strap extends along a path that first loops around the first anvil and then passes along the convoluted path.
