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.

A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

A reinforcement structure (10) comprising: (i) one or more members (12, 12A, 12B), the one or more members having one or more projections (20) extending from a base (16) of the one or more members; and (ii) one or more sleeves (28) surrounding the one or more projections (20) and secured to the one or more members, wherein the one or more sleeves and the one or more members are configured to crumple to absorb a force being applied to the reinforcement structure.

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 through 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.

An energy absorbing device is designed to increase the amount of absorbed energy and control the deformation of the device in case of an impact. The energy absorbing device consists in a hollow longitudinal member extending along a first longitudinal axis and a longitudinal guide extending along a second longitudinal axis, arranged within the longitudinal member and suitable for guiding the deformation of the longitudinal member in case of an impact. The length ratio between the longitudinal guide and the member is comprised between the values of 1/5 and 3/5.

A force damper arranged to progressively arrest a first force imparted by an object moving in a first direction is disclosed. The force damper includes a housing enclosure having a first housing end and a second housing end. The first housing end includes a first connection point, and the second housing end includes an opening. A driving member is disposed within the housing enclosure and includes a first shaft end, a second shaft end, and a shaft therebetween. The first shaft end includes a stop and the second shaft end includes a second connection point. A compressible member is disposed within the housing enclosure between the stop and the opening. The compressible member is formed from a material that at least partially undergoes plastic deformation when the first force is arrested and imparts a second force on the stop toward first housing end.

A steering column assembly includes a lower jacket assembly extending longitudinally from a first end to a second end and having an energy absorption (EA) plate. The steering column assembly also includes an upper jacket assembly at least partially received within the lower jacket assembly. The steering column assembly further includes an energy absorption strap integrally formed with the lower jacket assembly.

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.

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.
