STEERING COLUMN HAVING AN ENERGY ABSORPTION DEVICE
A steering column for a motor vehicle, having an inner casing tube which rotatably supports a steering shaft, and an outer casing unit in which the inner casing tube is received movably in the axial direction and is fixable, also having an energy absorption device which is arranged functionally between the casing tube and the casing unit, in which a portion of the energy occurring in the event of a crash can be absorbed when the casing tube is moved telescopically relative to the casing unit, wherein the energy absorption device comprises at least one deformation strip, which is pulled by a brake element and thereby deformed, is improved according to the invention in order to reduce the installation space of the overall steering column in that the deformation strip is fastened on a carrier plate, which in turn is fastened to the casing tube and projects in the axial direction beyond the casing tube.
MODULAR ENERGY-ABSORBING DEVICE
The present invention relates to a modular energy absorption device (9) comprising: a support (91) having fastening portions (81) forming single fastening points for fastening said device to a steering column, a deforming member (94) securely connected to the support, an absorber (93) coiled around the deforming member and fitted securely at each of its ends to the support, a coupling member (96) formed of a part separate from the support and having a first side securely connected to the absorber and a second side having at least a first engaging shape (96a),
said device being designed such that the exertion of forces in opposite directions on the support and on the tooth, respectively, brings about stress on the coiled portion of the absorber, tending to deform the latter.
Reach adjustable steering column assembly
A reach adjustable steering column assembly comprises a telescopic steering shaft which in use supports a steering wheel of the vehicle; a shroud that supports the steering shaft comprising an upper shroud part and a lower shroud part, the upper shroud part moving telescopically relative to the lower part during reach adjustment of the steering column assembly, a support bracket that supports the shroud relative to the vehicle body, and a clamp mechanism that is operable between an unclamped position in which the steering column assembly is adjustable for reach and a clamped position in which the reach position of the steering column assembly is fixed. The clamp mechanism comprises a first locking part that is displaceable by an actuator assembly into and out of positive engagement with a second locking part. An energy absorbing mechanism acts between the upper shroud part and the second locking part and is configured so that during a crash a deformable part of the energy absorbing mechanism is plastically deformed by a deforming part, thereby controlling the movement of the upper shroud part, and in that one of the deformable element and the deforming portion of the energy absorbing mechanism is secured to the upper shroud part, and the other is fixed relative to the second locking part.
Steering column assembly
A steering column assembly having a vehicle-fixed mounting element and a sleeve element received in the mounting element, which is mounted displaceably in the axial direction in the mounting element for adjusting the steering column assembly. The steering column assembly further comprises an energy absorption device which can be firmly coupled to the mounting element and is firmly connected to the sleeve element, the energy absorption device being deformed in the event of a vehicle crash in consequence of a longitudinal displacement of the sleeve element, and at the same time absorbing part of the kinetic energy of the sleeve element during the event.
STEERING COLUMN ASSEMBLY
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.
Steering column breakaway and energy absorption apparatus
An article for a steering column assembly (10) including a connection member (60) having a base portion (62) adapted to be attached to a column tube (30) of the steering column assembly (10) and opposing side walls (64) extending from the base portion (62). The article further includes an energy absorption member (80) having a first generally flat segment (82), a second generally flat segment (84) generally parallel to the first generally flat segment (82), and a curved portion (86) therebetween. The energy absorption member (80) extends from the base of the connection member (60). The present teachings also envision a telescoping adjustment subassembly and a steering column assembly (10) employing the article.
GEAR WHEEL OF AN ADJUSTMENT DRIVE MECHANISM FOR A STEERING COLUMN AND STEERING COLUMN FOR A MOTOR VEHICLE
A gear wheel for an adjustment drive mechanism which has a ring gear which is attached coaxially circumferentially to the outside of a core element which has an axial passage opening, in which a threaded element is fitted, the latter having an axially continuous internal thread having at least one thread tooth running around helically. The threaded element is formed from a plastic as an injection molded plastic part, which is molded onto the core element on an inner wall of the passage opening.
Arrangement structure of electrical apparatus in electric automobile
To provide an arrangement structure of electrical apparatuses in an electric automobile which can realize space savings of a space housing a plurality of electrical apparatuses. An arrangement structure of electrical apparatuses in an electric automobile includes: a vehicle body having a driver cabin and a housing space provided forward of the driver cabin; a plurality of electrical apparatuses (junction board, charger, voltage converter, battery heater) housed in the housing space; and a frame body retaining the plurality of electrical apparatuses to overlap vertically, in which a specific electrical apparatus positioned more downwards than a predetermined position among the plurality of electrical apparatus is arranged more downwards as having a shorter length in the front/rear direction of the vehicle body, or as having a shorter length in the width direction of the vehicle body.
Steering column assembly
A steering column assembly includes a mounting bracket having a first arm and a second arm, a steering column and a locking device which is configured to be in a locking state or an unlocking state to selectively allow a tilt motion of the supporting housing and the steering column by applying or removing clamping force to or from the first arm and the second arm. The locking device includes a tilting bolt which is connected to the lever to rotate together with the lever and passes through the first arm and the second arm to be able to rotate between the locking state and the unlocking state and a first locking unit and a second locking unit which respectively operate in response to rotation of the tilting bolt and selectively apply clamping force to the first and the second arms.
Energy absorbing assembly of a telescoping steering column
A telescoping steering column is adapted to be supported by a vehicle structure. The telescoping steering column includes a jacket assembly and a jacket. The jacket is telescopically coupled to the jacket assembly along an axis. The jacket assembly and the jacket are adapted to collapse axially from a normal state to a collapsed state upon exertion of an axial force in a forward direction. The energy absorbing assembly includes a pin and a rupture member disposed axially adjacent to the pin. The pin is fixed to the jacket assembly and extends radially with respect to the axis and through a first opening defined by the jacket. The rupture member is part of the jacket, defines at least in-part first and second openings in the jacket. The rupture member is adapted to break as the jacket assembly and the jacket move from the normal state to the collapsed state.
