UNITED STATES PATENT OFFICE- EDWIN E. GRA IF, OF SOUTH BEND, INDIANA, ASSIGNOR TO THE STUDEBAKER CORPORATION, A CORPORATION OF NEW JERSEY.

VEHICLE-SEAT.

To all whom it may concern:

Be it known that I, EDWIN E. GRAFF, a citizen of the United States of America, and resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Vehicle-Seats, of which the followingris a specification. y his invention relates to seats for vehicles and, particularly, to spring seats or cushions for automobiles and similar vehicles.

Among the objects of my invention may be noted the following: to provide means by which a very prominent-front roll may be given to the cushions or seats of vehicles; to provide means by which the prominent front roll iven to cushions or seats may be made dura 1e and given substantial permanence; to provide means by which cushions with a prominent front roll may be made and formed independently of the frame great facility; to provide a structHrewherein the front wall, piping, front cushion roll, and other structural members of the cushion may be simultaneously stitched together and then applied to the frame and springs with a minimum number of operations; to provide means by which the bottom of the front roll and top of the front wall of the cushion or seat may be connected to, and

sustained by, the more rigid portion of the frame structure; and to-provide simple and effective structural means by which to accomplish, economically, the foregoing ob- 'ects.

With the above objects in view and others which will be detailed during the course of this description, my inventlon consists in the parts, features, elements and combinations thereof hereinafter described and claimed.

In order that my invention may be clearly understood, I have provided drawings wherein:

Figure 1 is a perspective view, partly in section, showing details of construction; Fi 2 is a sectional elevation showing position of the front wall and roll seat cushion; and

Fig. 3 is a detail of the front wall and cushion members, including piping covering and attaching means disposed so as to show the manner in which the several memthe the Specification of Letters Patent.

structure and applied to the latter with Patented June 24, 1919.

bers may be connected together as a preliminary to attaching the same to the seat-frame.

Referrin to the drawings, the numerals 1 and 2 in icate usual wires of astandard frame for cushion seats for automobiles, 3 indicating one. of the several banks of springs employed to resiliently support the seat, said springs being clipped at 1, in usual manner, .to the wire 2, and at 5 to the bottom 6 ofthe front wall of the cushion. A clip 7 is clamped at one end around the wire 1, and, at its opposite end, around the wire 2, and has a depending member 8 adapted to be clamped about the anchoring or retalnlng wire 9, it being understood that, in the seat construction, a plurality of clips 7,usually five,are properly spaced apart along the length of the frame. The wire 9 has no other connection to the seat-frame structure, although its ends may be anchored, if desired.

doubled or folded so as to produce a pocket 10 for the filling and provide an edge or piping in which a wire 11 or other stlfi'ening may be inserted, and to which the bottom of the springs 3 is connected. At the free upper edges of the said front wall strip,

a narrow folded strip 12 is applied, forming a loop for the reception of the wire 9, the connection being made by several lines of stitching, such as 13 and 20, Fig. 3. The

wire may be confined in a pocket of the loop, if desired, formed by a line of stitching 14.

The loop 12 is provided with a plurality of slits or openings 15, through which the depending clip members 8 are inserted fore being clamped around the wire 9. Another short folded strip 16 is provided as a piping, beading or finish at the junction of the seat cushion with the front wall, the free edges of which arearranged at the outside of the wall strip at the free edges thereof. The seat cushions and front roll are made frompieces 17 18, 19 constituting the covering, lining or cushion pocket members and the usual burlap strip or strips extending over the springs, the cotton, hair ing 16, pocket 10 and 10031) 12, are superposed and placed with their e ges all pointing in the same direction, Fig. 8, and then simultancously stitched together by hues of ' stitchin 13 and 20. This is important, since fiy seat materials cannot be passed the bul under the machine arm, and the cushions and other members are made independently of the frame and applied thereto after completion. As shown 1n Figs. 1 and 2, the front roll 21 of the cushion is madevery prominent and drawn far forward so as to extend around the front wire 1 of the seat-frame, said cushion being formed by the lining or inner member 18, and the burlap or other inner member 19, the lining 18 being secured to the member 19, as at 22, so as to form a very lar e pocket for the filling. The pronunence of the roll 21 is increased by mserting filling 23 between the cover 17 and the member 18, to which latter a plurality of s tr1ps 24, 25 may be secured to form additional pockets for different kinds of fillin 23, 26,

27, which may be found desirab e. The cushions are now ready to be laced upon and secured to the seat-frame. 0 that end, the wire 9 is now slipped into the poclcet of the loop 12, and the clips 5 are a plied to the bottom of the front wall an bottom coils of the front springs. The ends of the extension members 8 are then ushed through the slits or openings 15 in t e loop 12, and twisted about wires 9, after whic the cushion members are turned over upon the seat-frame and secured upon the latter in the usual manner.

From the foregoing it will be seen that I have provided a cushion seat, the front wall A of which is substantially vertical, while the front roll is quite prominent. Such prominence is maintained, under all conditions of use, by anchoring the unction-loop 12 to the auxiliary wire 9, instead of to some part of the seat-frame; and the disposition of the auxiliary wire, adjacent the wire. 2, remote from the front of the seat-frame, not only provides a convenient means for attachment of the loop, but enables the junction-seam to be drawn well under the seat-frame and cushion, thus also drawin the front cushion well forward and aroun the front frame wire. By this means I can also ve any predetermined forward thrust to t e front cushion and regulate the prominence of the front wall, since the width of the loop 12 can be varied as described. Furthermore,

the piping 16, forming the finish and pro-.

tection for the seam at the junction of the front roll with the front-wall of the cushion, is back under the seat where it receives little or no wear and abrasion, thus retainin its good appearance throughout the life 0 the cushions. It will also be seen that, by providin the supporting wire auxlliary to the seatrame, as a means of attachment lieved from bending for the front-wall, the latter is anchored and held quite firmly in place and retained substantially in its normal sition durmg the use of the seat. By attac ing the loop to the front-wall at 13, below the line of the main seam 20, considerable strain upon the latter is avoided in the use of the seat. The wire and loop, as an anchoring means, are imrtant, since, under pressure .upon the cushlons, the loop will ive to some extent, and, according to its width, will operate more or less to sustain the upper edgeof the front wall and prevent the same from bein forced outwardly. The auxiliary wire and olding loop also constitute a means which help to retain the good form of the prominent frontroll of the cushion, since the latter is drawn well around and under the front of the seatframe, but cannot be unduly forced downwardly. This prevents wear and abrasion upon,the materials of the seat and undue stress upon the front wire of the frame. In fact, the said front wire is ver greatly restrain, t us enablin the seat to maintain its sha e and form much longer than is possible wit rior structures known to me. Another important feature of my invention resides in combining the several cushion members and parts indegendently of the seat-frame; that is to say, y assembling the cushions and other members thereof and stitching them together as described, I am able 'to machine-stitch the same as a preliminary to attachin them to the seat-frame, it being impossib e to machine-stitch the members to ether when assembled upon the frame. T is saves a eat deal of expense, since time is saved, lai orious handling of heavy parts is avoided, and assembhng is greatly facilitated.

Havlng thus described my invention, what I claim and desire to secureby Letters Patent 1s:
