Abstract: The roll-up heating (1) for a floor, or wall, comprises an insulating layer (10), a heating element (11) and a cladding (12). The insulating layer (10) is intended for laying on a floor (2) and the heating element (11) extends between the cladding (12) and the insulating layer (10). The cladding (12) is intended to support a floor covering and comprises a force distribution layer (13) for transmitting a force which is exerted on the cladding (12) in a distributed manner to the insulating layer (10). In as far as (a part of) the heating element (11) is at the location or in the vicinity of the exerted force, the load which will be exerted on it will be lower than the original load, due to the force being transmitted in a distributed manner. This lowers the risk of the heating element (11) being damaged.

Abstract: An automotive electrical wiring harness for connecting the electrical system of a towing vehicle to that of a trailer or the like has a flat connector at one end which is foldable along a hinge line of weakness in the body of the connector. When folded, the connector body is smaller than the diameter of a small opening in the bumper of the towing vehicle so as to permit the connector to be passed through the opening while the rest of the harness stays behind. Once on the far side of the opening, the connector is unfolded to reestablish its original flat, full size configuration, whereupon it may be coupled with other connector components of the vehicle's electrical system. Optionally, a protective sleeve may be slipped over the connector and frictionally retained in place thereon once the connector has been passed through the opening, so as to maintain structural integrity of the connection and to guard against the ingress of moisture and contaminants.
