Abstract
Abstract A snow mat series is positioned in surrounding relationship relative to an associated automotive vehicle to effect melting of snow surrounding the vehicle to accommodate access thereto. The apparatus is positioned along a portion of the vehicle as required. The mats may be formed of a rigid housing construction or of a cellular construction that permits the melting snow to be directed through the cellular matrix of each mat.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
259 words
A snow melting heater mat apparatus, comprising, a plurality of rigid heating mats, and an electrical power supply directed to a first of the rigid heating mats, the rigid heating mats arranged in a serial aligned orientation relative to one another to define an integral surrounding side wall, with each heating mat including a plurality of serpentine resistance heating members secured to each heating mat within the side wall of each heating mat, and a flexible connector cable directed between adjacent heating mats, with the flexible connector cable in electrical communication between the serpentine heating members of the adjacent heating mats, and each flexible connector cable includes a coil spring arranged in surrounding relationship relative to each connector cable, with each coil spring mounted at each distal end to the adjacent heating mats, and each heating mat includes a plurality of parallel first wall members orthogonally intersecting a plurality of second wall members defining cellular openings directed in a parallel relationship within the surrounding side wall, with the serpentine heating members mounted to upper distal ends of at least one of the first wall members and to at least one of the second wall members, and a first magnetic mounting block and the surrounding side wall is formed of a ferrous rigid material, and a tether cable secured to the first magnetic mounting block, and a second magnetic mounting block secured to said tether cable spaced from the first magnetic mounting block for securement to an associated vehicle to effect spacing of the heating mat relative to the vehicle.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
57 words
An apparatus as set forth in claim 1 including a flexible securement web secured at a first end to the continuous side wall of at least one of the heating mats, and a second distal end of the flexible securement web including a rigid securement tube secured coextensively to the second end of the flexible securement web.
Claim 4
Dependent Claim
50 words
An apparatus as set forth in claim 2 wherein the rigid securement web tube includes a tube cavity contained coextensively therethrough, with a signal flare cylinder slidably mounted within the tube, with the tube arranged for positioning within the associated vehicle between the vehicle and a door of the vehicle.
