Abstract
A seat attachment system for a mass transit vehicle including a rail, a fastener and a seat interface. The rail, which is adapted to be secured to a chassis of the mass transit vehicle, has a longitudinal T-slot adapted to receive the fastener. The rail has two non-parallel sets of corrugations on its external face. The seat interface, which is adapted to be mounted to a seat frame, is also provided with two non-parallel sets of corrugations whose angle matches that of the sets of corrugations on the rail. The sets of corrugations are adapted to cooperate and interlock in pairs so as to respectively locate the seat interface, and thereby a seat to which it is attached, vertically and horizontally upon the fastener being tightened.
Claims11
A seat attachment system for a mass transit vehicle comprising:
- a rail adapted to be secured to a chassis of the mass transit vehicle, the rail having a longitudinal T-slot, the T-slot defining a first shoulder and a second shoulder each located on one opposite side of a narrow portion of the T-slot, the rail having a first set of corrugations extending longitudinally on an external face of the first shoulder and a second set of corrugations on an external face of the second shoulder, the second set of corrugations being non-parallel to the first set of corrugations;
- a fastener, the fastener being adapted to be received within the T-slot;
- a seat interface adapted to be mounted to a passenger seat, the seat interface having a third set of corrugations extending longitudinally along a first portion of the seat interface and a fourth set of corrugations extending on a second portion of the seat interface, the third set of corrugations being adapted to cooperate with the first set of corrugations and the fourth set of corrugations being adapted to cooperate with the second set of corrugations,
- wherein:
- the second set of corrugations is at a predetermined angle from the first set of corrugations and the fourth set of corrugations is at the same predetermined angle from the third set of corrugations, the third set of corrugations being operative to vertically locate the seat interface by interlocking with the first set of corrugations upon a compression force being developed by the fastener being tightened, the fourth set of corrugations being operative to locate horizontally the seat interface by interlocking with the second set of corrugations upon the compression force being developed by the fastener being tightened.
