Bellows for protecting lower part of driver seat in e.g. lorry, has panels whose edges are fixed in pairs, where bellows are formed from plastic-coated fabric, and fixation between panels has wavy shape having number of troughs and crests

摘要

The bellows (1) have a front panel (10), left panels (20, 40) and a rear panel (30) that are fixed in pairs by their left side edges (11, 21, 41, 31) and right side edges (12, 22, 42, 32) to form a sleeve opened at its two ends (2, 3), where the bellows are formed from fire retardant material i.e. plastic-coated fabric. The fixation between the panels has a wavy shape having number of troughs and crests, which is equal to number of entering and leaving folds (4, 5). The folds are marked by a stitch. A slot is formed in one of the panels for allowing passage of seat adjusting levers. An independent claim is also included for a method for fabricating bellows.
