The frame has a chassis (2) with at least two tubular fixing profiles (3). The inside wall (3a) has a longitudinal slot (3d). At least one inflatable bladder (4) is arranged perpendicular to the fixing profiles, and attached through fixing elements (6) that slide in the longitudinal slots to allow an adjustment in position.A translational locking arrangement for each fixing profile uses an inflatable locking cushion (9) arranged inside the profile. It provides a simultaneous locking of all the fixing elements which are arranged to normally slide in the longitudinal slots.
