Steering column - Wikipedia

The steering column still consists of a long shaft connecting the collapsible steering column wheel to the steering gear box. In simple terms, the column is comprised of an inner and outer sleeve with a number of bearings contained between each sleeve. An opening is thus defined in the housing of the telescoping motor sub-assembly which allows it to break free from the fastener in the event collapsible steering column impact exceeding a predefined load is experienced.

The bracket may include a collapsible steering column that cooperates with one or more other structural elements e. Other approaches may be employed as well. For example, instead of tines, a thinned section or a section otherwise configured to rupture upon exposure to the predefined load may be employed.

Structures such as shown in U. The teachings also envision employing at least one plastically deformable energy absorption device collapsible steering column e.

The energy absorption device may have one free end and an attachment portion spaced from the free end that is fixed in place e. For example, the energy absorption device may be such collapsible steering column the attachment portion is located at an opposite end from the free end.

The energy absorption device may be an elongated metallic member. The energy absorption device may have at least one relative flat surface.

The energy absorption device may have opposing generally flat surfaces. The energy absorption device may be a metallic strip. Optionally the strip may have an elongated slot along at least a portion of collapsible steering column length.

For example, a slot may be employed to receive a fastener, a tang or some other structure for securing the strip in the assembly. The strip may have a free end that is closed.

As seen, the strip may be a folded plastically deformable energy absorption strip having a first downward disposed bend portion, a first elongated portion that is generally parallel with the column housing flange and disposed below it, a second bend portion that folds the strip around the rearward facing end of the column housing flange and a second collapsible steering column portion that is generally parallel with the first elongated portion and disposed about the column housing flange.

The energy absorption device may be collapsible steering column to be wider in cross-section than it is tall e. It may have a bulbous free end. The energy absorption device element may have a thickness that ranges from about 0.

The energy absorption device may be made of a steel e. In one aspect, the energy absorption device element may be such that it will be disposed within or carried on at least a portion of the telescoping motor subassembly.

For example, it may be such that it folds over and bears against a bearing end of an h-bracket or like structure.

It may be such that it is otherwise secured to an upper surface of the telescoping motor subassembly. For example, it may have an end that is folded to be received in a slot of the telescoping motor subassembly.

During a secondary impact, upon attainment of a predefined load, the energy absorption device element may initially translate, elastically deform, and after a collapsible steering column load has been reached will begin plastic deformation e.

Such plastic deformation is envisioned to contribute substantially to absorption of energy from the secondary impact.

How Collapsible steering column works ?

The energy absorption device element may be fastened at one or more locations along its length to another structure collapsible steering column the assembly e. Examples of suitable devices collapsible steering column can be employed for an energy absorption device include those as described in U.

Thus, the elements as described may be assembled in a manner to achieve the described assembly. The teachings envision providing an assembly as described herein for installation into an automotive vehicle.
