Abstract
Abstract A seat base having protruding members fixed to the underside thereof that are positioned within mating recesses formed in the fenderdeck of a vehicle. The base is clamped to the fenderdeck by a pair of screws. The screws and mating features defined between the seat base and fenderdeck secure the base to the vehicle to prevent shifting of the seat during operation. If the screws become loosened during operation, the protruding members will engage side walls of the recesses to prevent the base from shifting fore and aft suddenly and unexpectedly, and to alert the operator that the screws have become loosened.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle; a second member fixed with the seat and in engagement with the first member; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having tightened and untightened positions; means for preventing fore and aft shifting of the second member relative to the first member when the clamping means is in an untightened position, said means for preventing including a portion connected with the second member in operative engagement with a portion of the first member.
Claim 2
Dependent Claim
109 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle; a second member fixed with the seat and in engagement with the first member; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having tightened and untightened positions; means for preventing fore and aft shifting of the second member relative to the first member when the clamping means is in an untightened position, said means for preventing including a portion connected with the second member in operative engagement with a portion of the first member.
Claim 3
Dependent Claim
120 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle; a second member fixed with the seat and in engagement with the first member; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having tightened and untightened positions; recesses formed in one of the members and staggered fore and aft with respect to the vehicle; a protruding member formed in the member that does not have the recesses, said protruding members being selectively positionable within the recesses for hindering fore and aft shifting of the first member when the clamping means is in its untightened position.
Claim 4
Dependent Claim
120 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle; a second member fixed with the seat and in engagement with the first member; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having tightened and untightened positions; recesses formed in one of the members and staggered fore and aft with respect to the vehicle; a protruding member formed in the member that does not have the recesses, said protruding members being selectively positionable within the recesses for hindering fore and aft shifting of the first member when the clamping means is in its untightened position.
Claim 5
Dependent Claim
102 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle and having recesses staggered fore and aft with respect to the vehicle; a second member fixed with the seat; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having a tightened and an untightened position, and protruding members formed in the second member and selectively positionable within the recesses for hindering fore and aft shifting of the first member when the clamping means is in its untightened position.
Claim 6
Dependent Claim
102 words
A mechanism for attaching a seat to a vehicle, said mechanism comprising: a first member fixed with the vehicle and having recesses staggered fore and aft with respect to the vehicle; a second member fixed with the seat; clamping means for frictionally securing the first member to the second member to prevent fore and aft movement of the second member, said means having a tightened and an untightened position, and protruding members formed in the second member and selectively positionable within the recesses for hindering fore and aft shifting of the first member when the clamping means is in its untightened position.
Claim 7
Dependent Claim
50 words
The invention of claim 3, and further comprising: a first recess formed in the first member and offset from the clamping means; a second protruding member fixed with the second member and positionable within the second recess for preventing lateral shifting of the second member relative to the first member.
Claim 8
Dependent Claim
13 words
The invention of claim 3, wherein the second member is a plastic material.
Claim 9
Dependent Claim
16 words
The invention of claim 3, wherein the first member is a fenderdeck carried by the vehicle.
Claim 10
Dependent Claim
