vBACK REST Fon BLEACHER SEATS.

' Appiiuon mea August s, 1925. serial No. 49,074.

The object of this invention is to provide a back rest that can be quickly and easily attached to any seat which is not provided with a back rest as, for instance, .the bleacher seats of grandstands, circus seats, etc.

A further objectA is to provide a device of this character which is of such simple construction that it may be sold at such a low price that it may be cast aside when thel period of use is ended.

A still further object is to provide a back rest which is light, compact, which is adjustable to different seats on which it may be used, and which is also adjustable to different angles of inclination.

Myy 'nvention is illustra-ted in the accompanying' drawing, lwherein v Figure 1 is a sectional vview through a seat with my back rest appliedv thereto, the back rest being shown in end elevation:

Figure 2 is a front view of the back rest and of the seat;

Figure 3. is a rear view of the back rest and rest; i Figure 4 is a perspective view showmg the seat engaging hook and the back rest supportingv cord.

Referring to this drawing, it will be seen vthat I have shown my back as applied to a bleacher seat A which is meantto be illustrative of any seat without a back. My device comprises a back board 10 which may be made of any suitablev material and of any degree of lightness which will give the proper strength. Attached to the back adjacent its upper end is the transverse cross bar 11 which projects beyond the back on each side.

vExtending across the rear face of this back rest is a cord, chain 'or other fiexible member 12 which, adjacent thefends of the cross bar 11 or brace, passes through eyes 13. The ends 14 ofl this cord 12 are flexible and in the use ofthe device extend toward the forward edge of the seat and thus act as a support for thej back rest and the ends of these portions 14 of the cord 12 are knotted at a plurality of points, as at 15.

Coacting with these knots and disposed in the portion14 is a double hook 16, one bill of which is large enough to engage over the forward edge of the seat A. The upper or small bill of this S-shaped hook is relatively small and in effect just large enough for the passage of the 00rd or other flexible connection 14 but not large enough for -the tively wide, the hooks will be engaged with the voutermost knots 15 but if the seat A is relatively narrow the hooks will be engaged with the innermost knots 15, and that if it is necessary further knots may be tied in the flexible member so as to place the hooksstill nearer to the back. It is obvious that the back may be inclined at any desired angle to the seat A and held at this inclination by properly adjusting the hooks 17 upon the portions 14 of the supporting cord. The lower end of the back board can be moved forward or backward, depending on the angle of Iinclination desired, and my construction enables the back rest to be adjusted to different widths of seats and to different desired angles and positions.

I do not wish-to be limited to any specific material for the back-rest, nor to a specific form of flexible member 12 and 14.

1. A back rest for seats comprising a back proper, a fiexible member extending across the back and then adapted to extend downward and forward, the flexible member adjacent its free ends being formed with a series of knots, double hooks coacting with said free ends and adapted to engage the forward edge of the seat, each hook being formed with a relatively large seat engaging bill, and a relatively small member engaging bill.

` extend downward and forward, thev cord adjacent each of its free ends being formed with a knot, hooks coacting with said free ends and adapted to engage the forward edge of the seat, each hook being formed with a seat-engaging bill and a rope-engaging knot-engaging portion. l

3. A back rest for bleacher seats comprisf ing a back proper, a cross bar attached to the back and having eyes adjacent its ends, A

a flexible member passing through said eyes and .adapted to extend .downward and f or- K ward therefrom,v the downward and forward.

portions having .knots at their extremities,

an a double hookformed to provide ya large Abill and a small bill, the large bill being adapted to engage the forward edge of a seat and the small bill to receivefsaid exible member but being smaller than thevknots. t 4; A bleacher seat back rest comprising -a back, a transverse bracel attached to -the back,v

a cord assing across said brace and connected t creto and having end portions eX-' shaped portion and a relatively small hook-I shaped portion,' the latter being small enough to slideupon the cord but too small to permit the passage of the knots.

5.` A back rest for seats comprising-a back proper, cords'extending downward from the bank adjacent the upper endl thereof, and hooks mounted upon the ends of the cords, each rhook being formed to provide ya relatively large hooli portion adapted tol engagebeneath a seat, and a relatively small eye with which the corresponding cord is loosely engaged, each cord and the corresponding hook being formed with coacting means whereby the hook may be adjusted nearer to or further from the back.

In testimony whereof I hereunto afiix my signature. y v
