PCT No. PCT/AT83/00017 Sec. 371 Date Feb. 1, 1984 Sec. 102(e) Date Feb. 1, 1984 PCT Filed Jun. 8, 1983 PCT Pub. No. WO83/04397 PCT Pub. Date Dec. 22, 1983.In a sand-dispensing device for motor vehicles there is provided a refillable sand container, a sand channel with a sand outlet closable by a flap that opens downwards, and a heating system in the contact area of the flap at the sand outlet. This comprises an electrical heating wire that is provided in the contact area such as in the walls of the sand outlet or in the flap and/or in a gasket between the flap and the sand outlet. The heating system helps prevent the flap freezing shut on account of road spray, snow and cold, and thus preserves the functional capability of the sanding system. |
