Abrégé

A coupler pivot. A coupler (10) comprises at least a first gimbal (31; 32) defining a pivot that is secured to a mounting (41) for securing to a frame member of a vehicle, the pivot also being secured to a buffer column (39) part of which protrudes on an opposite side of the pivot to the mounting (41) such that the buffer column (39) is moveable relative to the mounting (41) with at least two degrees of freedom. The buffer column (39) defines a free (42) end that is remote from the mounting (41) and that is securable to a further member. The buffer column (39) also includes both a reversible buffer that attenuates buff and draft forces acting between the free end (42) and the mounting (41) and also a non-reversible buffer that attenuates buff forces acting between the free end (42) and the mounting (41) and attaining or exceeding a predetermined energy threshold, the reversible and non-reversible buffers overlapping over at least part of their lengths in the buffer column (39) which in turn overlaps at least one of the pivots.

Abrégé

A buffer comprising a first, elongate buffer element that is moveably received within the interior of a second, elongate, hollow buffer element such that the first and second buffer elements overlap over part of their length, such that the buffer elements define a hollow interior of the buffer and such that at an end of the buffer at least the second buffer element is exposed for engagement with a respective, further member, the first and second buffer elements being moveable between a first, extended or intermediate configuration of the buffer and a second, compressed configuration, compression of the buffer more energetically than a threshold energy level causing the first buffer element to energize a non-recoverable energy absorbing member, forming part of the buffer or capsule, to cause deformation of one or more plastically deformable parts of the buffer, characterized in that the non-recoverable energy absorbing member lies between the ends of the buffer at least in the region energized by the first buffer element.
