7 Claims.

This invention relates to seats in general and in particular to seats intended for use by motormen or for additional seating capacity during rush hours.

In the past seats of Aa general type have been constructed and hinged to the supporting structure in such a manner as to place a continual crushing pressure upon the cushioning material in the seat at all times when the seat was folded.

Seats of this type have also in the past been constructed with the upholstered portion more or less permanent requiring extensive repair Whenever the cushioning material needed replacement.

It is an object, therefore, of the present invention to provide a simple seat arrangement Wherein the seat may be readily removed for reconditioning and repair or replacement.

l A further object of the invention is the provision of a seat having' a frame which, together torting forces being applied to the cushioned material.

These and other objects of the invention Will be apparent to persons skilled in the art from a study of the following description and accompanying drawings, in which:

Figure 1 is a partial sectional view through a car showing the improved folding seat secured thereto; l

Fig. 2 is a front elevation of the folding seat and adjacent car wall or supporting structure;

Fig. 3 is a plan view of the folding seat shown in Figures 1 and 2;

Fig. 4 is a sectional view taken substantially on line 4-4 of Fig. 3 and showing details of the seatconstruction; and

Fig. 5 is a sectional view taken through the seat and showing details of the frame construction.

l Referring now to the drawings in detail it will be seen that the folding seat assembly is secured to a supporting structure such as a car Wall 2 above the heater or ventilatorduct Ilby means of hinge elements 6 and 8. In the present instance there are two hinge elements 6 adapted to receive hinge pins I0 extending through hinge elements I2 carried at the rear edge of the seat base plate I4. The seat base plate is pressed, or otherwise formed, from a single sheet of metal stiffened by downwardly directed front and side flanges I6 and has punched, or otherwise formed, in the upper surface a plurality of holes I8 adapted to receive J bolts 20 later to be referred to. The base plate is also provided-with lugs 22 adjacent its forward edge, which lugs are adapted to receive bolts or other means 24 pivotally carrying the ends of U-shaped supporting member 26. This U-shaped supporting member is preferably formed from an angle element having flanges disposed at right angles to each other with one flange 28 extended to receive the hinge bolts just referred to, while the other flanges 30 are directed toward each other and interconnected by means of a brace plate 32. The brace plate or bar has secured thereto substantially at its center a'hinge member 34 adapted to receive bolt or pin 36 pivotally carrying one end of tie bar 38, the other end of which is pivotally carried by bolt or pin 40 extending through hinge element 8 previously referred to.v In order to prevent injury to the floor, eliminate noise and absorb the shocks incident to lowering of the seat a rubber or other resilient buffer block 42 is bolted or otherwise secured to the Web portion of the U-shaped supporting member.

The upholstered portion of the seat or cushion is formed by a plurality of wooden or other frame members 50 having their ends notched as at 52 and secured together by nails or other securing means 54 (Figs. 3 and 5). As clearly shown in Figs. 4 and 5 these frame elements have their upper surfaces rounded as at 5S and are provided with transverse holes 58 adapted to receive the shoulder portion 60 of the J bolts, while the shank portion thereof vis adapted to extend downwardly through the holes I8 in the base plate and receive nuts 62 by means Yofwh'ich the frame may be securely held upon the base plate. After the frame isl completed va self-sustaining resilient main cushioning element '64, preferably made oi sponge rubber, such asthat soldl under the trade name of Dunlopillo manufactured and sold by the Dunlop lTire and Rubber Company of Buffalo, New York, is inserted inthe frame with its upper surface projecting thereabove, and'with the sides frictionally engaging the frame to hold the cushioning element in position. With the main cushioning element in position an auxiliary cushioning or padding element `66, preferably of some felt material, is laid over the frame and main cushioning element, after which a fabric,

artificial leather or similar cover 68 is applied into the space within the frame thus requiringv notching of the main cushioning element. Such a construction is desirable in order that the main cushioning element may be readily removed from .the frame without disturbing the auxiliary cushdamaged suciently to require replacement, a

new element may be readily inserted in the frame after the J bolts have beenreplacedinthe openings provided for the same in the wooden frame.

Attention is directed to the fact that' the hinge elements I2 are offset downwardly from their hinge pins as clearly shown in Fig. 1 in order that the seat when folded will have the top sur-l face of the cushion substantially parallel to the wall ror supporting structure, in which folded position Kline and dash Figc, 1 it is retained by means of locking hook 80 eng-aging over the seat base plate iiange and pivotally carried by the car wall or other supporting structure.` With theyseat in the'folded position release of the hook will permit the seat to swing outwardly and downwardly with the tie bar 38 positively placing the U-shaped support member 26 in its Yproper position and with the shock being absorbed by the vresilient buffer block upon -the lower edge of the support member.

WhileA the construction has been described more or less in detail, it is obvious that various modifications and; rearrangements of'parts may bey made without departing from the scope of lthe invention as defined bythe following claims.
