AUTOMOBILE SEAT AND THE LIKE Original Io. 1,088,889, dated September 4, 1928, Serial No. 122,321, flied July 14, 1928. Application reissue fled December 80,

This invention relates to improvements in automobile sea-ts, having particular reference to rotatable single seats arranged to fa- .cilitate the entrance of a person into an automobile, or facilitate their exit therefrom.

The improved seats are particularly adaptable for the coach type of automobile in which only one door is used on a side, entrance to the rear seat being attained by rotating the 10 side front seat to open a passage between the seat and the side of the car,thus making it possible for others to pass to or leave the car from the rear seat when the front side seat is occupied merely b the occupant of the front seat'moving with the seat rotatably. When the front side seat is unoccupied the passage to the rear seat is opened in like manner by rotatin the side seat.

The present invention differs from the construction set forth in my copending ap lication herein referred to in structural yeatures and in operating independently of the door. The improved seat as herein set forth has been simplified and cheapened for production in quantities the same being adapted and having merit as standard construction for any make of automobile of the coach type or any type of automobile in which separate front seats are used.

The invention is illustrated in its preferred form in the accompanying drawings in which:

Fi 1 is a sectional view in elevation of the nt end of an automobile coach, lookas ing toward the front of the car'with the improved seat turned at an angle;

Fig. 2 is a diagrammatic view of the front seats illustrating the difierent positions of the rotatable seat;

e improved seat as here shown, relates entirely to the rotatable base construction of the front side seat of the coach, consisting of 6 the floor base 1 which is concaved on its lower Fi 3 is a view in side elevation of the ro- 1 1929. Serialli'o. 417,578.

face thus presentin a rim or annular flange 2 upon the edge 0 whichthe base rests on the floor of the car. Opposite widely spaced bearing arms 3 are formed integrally with base 1 and are pivoted at their front ends in brackets 4 secured to the floor of the car, the connection between the brackets and arms 3 being effected by means of sleeve bearings 5. Thus the seat as a whole is adapted to be turned forward in the manner common to front side seats of this character.

Supported rotatably on the floor base 1 is a one piece seat basefi, the two bases being assembled one with the other by a bolt 7 about which the upper base is free to rotate. A ball bearing 8 is interposed between bases 1-6, the bearing race being formed by annular grooves 9--10 formed in the upper and lower bases respectively near their coacting outer edges as best shown in Fig. 3, thus acting to minimize friction in the bearing.

The upturned wall of base 6 is higher at the front than at the rear, the inclination of the wall to the rear serving to give the desired angle to the seat. The upper portion of the base is shaped into a shoulder or ledge 11 which serves as. a seat for the cushion 12 and a flange 13 which acts to retain the cushion, the under frame structure of the cushion being secured to the base by screws 14. The back 15 is standard construction except as to fastening the hinge bracket to the flange of base 6.

Provision is made, as best shown in Fig. 4, for latching the seat in its normal position, also when the seat is turned a half turn to face the rear seat thus to prevent rotatable movement of the seat in either position when the car is in travel. The seat latching mechanism consists of a latch member 17 pivoted on a forward extension 18 of base 1 as at 19, the finger 20 of the latch coacting with notches 21-22 in base 6 to retain the seat in its two positions accordingly as the occupant of the seat may wish to face forward, or rearward.

The opposite end of pawl 17 is connected pivotally to a sleeve 23 slidable on a push rod 24 having slidable bearingsupports in the sleeves 5 and spring tensioned toward the .door adjacent the rotatable seatby springs 25. One of the springs is compressed between one of the bearing sleeves 5 and a collar 26, and the other spring between the sleeve 23 and another collar 26, both collars 26 being pinned to the push rod 24. A third collar 27 butts against the opposite end of' sleeve 23 is moved axially under the spring tension toward the door, when the door is opened, to move pawl 17 on its pivot, disengaging base 6, the seat being then free to rotate. The inner end of the push rod is provided with a head 28 to limit the movement of the rod. The outer end of the-rod is threaded as indicated in Fig. 5 and is provided with an axially extendible head 29 adapted to butt against the adjacent door of the car when the door is closed, the door being provided as shown in Fig. 1 with a'plate 30 to engage the head 29. When the door is closed rod 24- is pushed inward thus acting yieldingly through spring 25 and collar 26 coacting with the pawl to cause the pawl to engage notch 21, when the seat is turned forward, or notch 22 when the seat is turned rearward, the position of the parts being then as illustrated in Fig. 4. When the door is opened springs 25 act to move the rod in the opposite direction and thus to disengage pawl 17, the seat being then free to turn. The arrangement of the spring 25 coacting with sleeve 23 and collars 26-27 is such that the latch 17 will not be jambed if the door is closed when the seat is turned at an angle, the latch being then out of engagement with the notches 21-22,

, compensation for the abnormal relation of the parts being rovided b the sprin s 25.

It will be obsdi'ved in Figs. 1 and 2 that ample space is provided for entrance to the rear of the car when the side seat is turned as indicated. When the seat is occupied the occupant turns wit-h the seat moving the body to present the seat at the required angle to open the assage.

Both t e function and structural merits of the invention will be readily a parent to those familiar with the seat and door arrangements of automobile coaches. The few and simple parts adapt the invention for low cost production and the substantial construction, ease of operation and effective control of the mechanism insures its normal operation under the conditions of use. The main parts are designed for reduction from sheet metal from dies to 0 tain maximum strength with minimum weight, neatness of appearance and production at the lowest possible cost.
