Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A vehicle seat structure having a support member, a ridercarrying seat member, and yielding suspension means including a movable member carrying the seat member on the support member for relative up and down movement, characterized by lock means for selectively positively locking the seat member against both up and down movement and for releasing the seat member for up and down movement, said lock means including an element pivoted on and carried by one member and having an elongated slot therein and a second slot angled to the elongated slot, another member has a guide carrying the element by means of the elongated slot when the seat member is released for up and down movement, and control means for effecting relative shifting movement between said element and guide for receipt of the guide in the angled slot so as to lock the seat member against up and down movement.
Claim 2
Dependent Claim
149 words
A vehicle seat structure having a support member, a ridercarrying seat member, and yielding suspension means including a movable member carrying the seat member on the support member for relative up and down movement, characterized by lock means for selectively positively locking the seat member against both up and down movement and for releasing the seat member for up and down movement, said lock means including an element pivoted on and carried by one member and having an elongated slot therein and a second slot angled to the elongated slot, another member has a guide carrying the element by means of the elongated slot when the seat member is released for up and down movement, and control means for effecting relative shifting movement between said element and guide for receipt of the guide in the angled slot so as to lock the seat member against up and down movement.
Claim 3
Dependent Claim
59 words
The invention defined in claim 1, further characterized in that the element is biased so that the top edge of the elongated slot normally rides on the guide, the angled slot depends from the elongated slot, and the control means is operative to elevate the element relative to the guide to receive the latter for locking the seat member.
Claim 4
Dependent Claim
70 words
The invention defined in claim 1, further characterized in that the element is so pivoted to the one member that it tends to swing downwardly by gravity, the top edge of the elongated slot normally rides on the guide, the angled slot depends from the elongated slot, and the control means is operative to elevate the element relative to the guide to receive the latter for locking the seat member.
Claim 5
Dependent Claim
45 words
The invention defined in claim 3, in which the control means is movable between lock and release positions, a link means is connected between the control means and the element to move the element upwardly when the control means is moved to its lock position.
Claim 6
Dependent Claim
33 words
The invention defined in claim 4 in which the link means includes a resilient connection for imparting a lifting bias to the element when the control means is moved to its lock position.
Claim 7
Dependent Claim
23 words
The invention defined in claim 4, further characterized in that releasable means is provided for holding the control means in its lock position.
