Independent Claim
72 words
A device for connecting together at least two persons while skiing one behind another for facilitating the movement of the skier or skiers to the rear comprising at least two harnesses adapted to be worn by consecutive skiers, towline means connecting two consecutive harnesses in front to back relation, said towline means including safety coupling means adapted to disconnect the two skiers when a predetermined tension is exerted on said towline means.
Claim 2
Independent Claim
72 words
A device for connecting together at least two persons while skiing one behind another for facilitating the movement of the skier or skiers to the rear comprising at least two harnesses adapted to be worn by consecutive skiers, towline means connecting two consecutive harnesses in front to back relation, said towline means including safety coupling means adapted to disconnect the two skiers when a predetermined tension is exerted on said towline means.
Claim 3
Dependent Claim
15 words
A device as in claim 1 and wherein said towline means includes an elastic portion.
Claim 4
Dependent Claim
50 words
A device as in claim 2 and wherein said towline means comprises two inelastic portions including a front cord portion comprising one of said inelastic portions connected to the rear of the lead harness and a rear cord portion of V shape having both ends connected to the trailing harness.
Claim 5
Dependent Claim
34 words
A device as in claim 3 and wherein said elastic portion is backed up by a third inelastic portion of greater length than said elastic portion when relaxed and connecting said two inelastic portions.
Claim 6
Dependent Claim
25 words
A device as in claim 3 or 4 and wherein said safety coupling means connects said elastic portion and the rearmost of said inelastic portions.
Claim 7
Dependent Claim
