A berth or bunk for cabs of industrial vehicles and the like, positioned behind the driver\s and passenger\s seats. The bunk is so structured as to be easily deformed in case of a road accident by the thrust created by the rearward motion of the seats, when a device for automatic or manually-controlled rearward motion of the seats is activated, to contribute to the safety of the driver and the passenger.

A berth of the type hinged onto the rear wall of a cab of a vehicle equipped with a safety apparatus for moving the vehicle seat rearwardly in the event of a front end collision comprising: a planar board having a metal honeycomb-like structure including a plurality of cells of substantially tubular shape positioned with their central longitudinal axis perpendicular to the plane of said board, such that said board has high flexural strength for supporting the weight of a person thereon, and high deformability in the direction perpendicular to said central longitudinal axis of said cells, thereby allowing a seat in the cab, moving rearwardly as a result of a front end collision, to easily deform said board without encountering substantial crushing resistance from said berth, said board having a main section and an initial section having a cross-sectional area less than that of said main section, said initial section thereby having a structure more easily deformable than said main section, said initial section being integral with said main section and disposed adjacent to the seat, said board thereby exhibiting a decreasing deformability under impact by a rearwardly moving seat.
