Abstract

A cab side wall mounted seat support has a slide assembly, typically a bar and sleeve assembly, attached to the wall and coupled by an upper arm support to a seat socket. A lower arm has a peg which engages one of a series of holes in the wall for locking the seat in place. The slide assembly includes a rotation function allowing the socket to be raised to release the peg from the hole for seat adjustment. Alternatively, the upper arm support is hinged to permit such release. One embodiment uses a roller on the lower arm instead of the peg and a spring loaded locking pin in the slide assembly releasably holds the seat in place.

Claims

1. A seat support for attachment to a locomotive cab side wall having a series of apertures in the wall and adapted for fore and aft sliding adjustment, comprising:

wall bracket means;

a seat socket for holding a seat;

a diagonal brace extending from the seat socket to an aperture in the wall for holding the seat socket against sliding adjustment;

a lateral support coupled to the wall bracket means and extending from the wall bracket means to the seat socket, the support including a bar and sleeve means for sliding adjustment and for tilting to release the diagonal brace from the said aperture; and

the lateral support including arm means extending from one of the bar and sleeve means to the seat socket.

2. The invention as defined in claim 1 wherein the bar is fixed to the wall bracket means and the sleeve means is fixed to the arm means such that the sleeve means slides on the bar to effect sliding of the arm means and the sleeve means rotates around the bar to effect tilting of the arm means.

3. The invention as defined in claim 1 wherein the sleeve means is fixed to the wall bracket means and the bar is slidably and rotatably disposed within the sleeve means, and the arm means is fixed to the bar to effect sliding and tilting of the arm means.

4. The invention as defined in claim 1 wherein the sleeve means is fixed to the wall bracket means and comprises a C-shaped cross section tube defining a slot along one side, the bar is slidably and rotatably disposed within the sleeve means, and the arm means is fixed to the bar and extends through the slot to effect sliding and tilting of the arm means.

5. The invention as defined in claim 1 wherein the arm means comprises at least one arm.

6. The invention as defined in claim 1 wherein:

the bar is fixed to the wall bracket means;

the sleeve means comprises two axially spaced tubes slidably and rotatably mounted on the bar; and

the arm means comprises two arms connected to the seat socket, each arm extending to one of the two axially spaced tubes.

7. The invention as defined in claim 1 wherein the bar and sleeve means are coupled by bearings for enhanced ease of relative movement.

8. The invention as defined in claim 1 wherein one of the bar and sleeve means connects with means extending laterally from one of said bar and sleeve means which allow relative axial sliding motion but prevent axial separation of the bar and sleeve.

9. A seat support for attachment to a locomotive cab side wall and adapted for fore and aft sliding adjustment, the support comprising:

wall bracket means;

a seat socket for holding a seat;

a diagonal brace extending from the seat socket to the wall below the bracket means for support and for releasably holding the seat socket against sliding adjustment;

a lateral support coupled to the wall bracket means and extending from the wall bracket means to the seat socket, the lateral support comprising arm means attached at one end to the seat socket and a pair of relatively sliding members attached to the wall bracket means and the arm means, respectively, the sliding members being mounted for fore and aft sliding to permit moving the arm means in the direction of adjustment; and

the lateral support having hinge means for permitting the seat socket to be tilted upwardly to release the diagonal brace from the wall.

10. The invention as defined in claim 9 wherein the hinge means is incorporated in the sliding members.

11. The invention as defined in claim 9 wherein the arm means is articulated to incorporate the said hinge means.

12. The invention as defined in claim 9 wherein one of the relatively sliding members connects with means extending laterally from one of said relatively sliding members which allow relative axial sliding motion but prevent axial separation of the sliding members.

13. A seat support attachment to a locomotive cab side wall and adapted for fore and aft sliding adjustment, the support comprising:

wall bracket means;

a seat socket for holding a seat;

a diagonal brace extending from the seat socket to the wall below the bracket means for support;

a lateral support coupled to the wall bracket means and extending from the wall bracket means to the seat socket, the lateral support comprising arm means attached at one end to the seat socket and at least one relatively sliding member attached to the wall bracket means and the arm means, respectively, the at least one sliding member being mounted for fore and aft sliding to permit moving the arm means in the direction of adjustment; and

locking means releasably holding the seat socket against sliding adjustment, the lateral support having hinge means permitting the seat socket to be tilted upwardly, moving the diagonal brace out of contact with the wall.

14. The invention as defined in claim 13 wherein the at least one relatively sliding member includes a bar and sleeve.

15. The invention as defined in claim 14 wherein the locking means is associated with the bar and sleeve.

16. The invention as defined in claim 14 wherein the locking means is associated with the diagonal brace.
