摘要:
A composite article comprises first and second members (20, 22) integrally joined together, one containing the other, or substantially so, and the first member (20) being of an expanded plastics material whilst the second member (22) is of a denser material having generally greater strength characteristics. Overall the article has an impact absorbing strength substantially greater than that of the first member. The first member may be of a polyurethane foam and the second member may be of a thermoplastics material, which may be vacuum formed to shape. The second member (22) may form an elastically deformable core element of the article covered by the first member (20). One form of the composite article is a bull bar or other protective bar of a vehicle which is capable of flexing upon impact, but also has sufficient strength to provide adequate protection to the vehicle. Other forms of the article include a baton and a twin sheet panel, which may be a vehicle body panel or body component.

The invention relates to a hoisting winch including: a frame (1) supporting (i) a drum (2) that can be rotated about an axis Δ in order to wind a cable or the like and (ii) a main drive system (5) for rotating the drum (2) in accordance with an instruction; a safety system (S) comprising a so-called hollow toothed wheel (12) rotatably secured to the drum (2) and a worm gear (13) that engages with the hollow wheel (12) and is rotated by a follower drive system; and control means designed to control the follower drive system in order to rotate the screw, allowing the rotation of the hollow wheel (12) according to the instruction for rotating the drum (2). According to the invention, the safety system (S) further includes: at least one brake disk (10) which can rotate about a rotational axis and supports the worm gear (13) and the follower drive system; and at least one brake caliper (25) which is attached to the frame (1) and includes a jaw (26) that is locked in a position in which it is clamped to the disk (10), but can be opened.

The invention relates to a covering item 1 for detecting droppages and comprises - a body 3 delimited by edges 5, 7, 9, 11, a plurality of pressure sensors 23 distributed in a chosen geometry within the body 3, a processing unit 27 connected to at least some of the pressure sensors 23 and designed to collect information regarding the state of these pressure sensors 23, and at least a first connector 15, 17, 21 and a second connector 19, each one connected to the processing unit 27, arranged near an edge 5, 7, 9, 11 and designed to be able to be connected to a connector of another, similar, item. The processing unit 27 is designed to associate location information drawn from said state information with information regarding the location of the item 1, to receive, via the first connector 15, 17, 21, information from a first other similar item, and to emit, via the second connector 19, the associated information and/or said information received, to a second other similar item.
