REVERSIBLE-SEAT MECHANISM.

Application filed July 19,

The present invention relates to sea-ts, particularly of the type designed for vehicles and of an improved form rendering them readily reversible.

More particularly, the invention relates to seats of the above type which are supported rotatably upon a pedestal and adapted to be locked in either position by a mechanism which permits the rotation of the seat as well .w as automatically positions it in either ahead or reverse direction.

An ob ect of the invention is to provide a construction which will permit bagga e to be carried under the seat and yet provi e the desirable features of a pedestal seat. From the standpoint of ease of adjustment, seats of the above type are highly desirable and failure to adopt them as standard installations has resulted from the fact that the 2 pedestal occupies too much room and 'pre- Vents luggage from being placed under the seat. The present invention, therefore, combines the advantages secured from seats of both types and results in a highly useful seat construction.

A further object is to provide a seat which may be rotated upon a pedestal but which, when in either position, is as solidly supported at its sides, as seats of the old form having end standards and unitary bases.

In this connection, the improved seat is formed to provide a locking and positioning means combined, the structures of each being so related that the locking operation is effected in proper sequence to the positioning of the seat.

Further objects of the invention will appear as the description proceeds and refer ence will now be had to the accompanying drawings, forming a part hereof, for a more detailed description of the invention, wherein:

Figure 1 is a plan view, partly broken away showing a preferred form of the invent-ion.

Figure 2 is a section, taken on line 22 of Figure 1, and looking in the direction of the arrows.

Reference character a designates the lower portion of the seat frame provided with a base a to which a downwardly extending bearing a is secured. At either end of the base a a bracket a is secured by means ofsuitable bolts a. The bracket comprises a downwardly extending portion having apertures a therein and grooves a in the sides thereof.

1927. Serial No. 206,815.

The brackets are formed generally arc-shaped about the pivot point of the base a, and serve to support the base frame at its ends. The plan view of Figure 1 shows the shape of these brackets and their relation to the hearing member a in the center of the base a.

Vertical standards I) and b are connected by a longitudinal bridge 6 having strengthening webs Z2 This structure is adapted to position the seat upon the floor and the bridge member 6 is provided with a downwardly extending housing 6 at its mid section. A suitable pedestal b is secured in the housing 6* and provided with a step bearing (2 A horizontal flange a is provided at the bottom of the vertical bearing a and carries, in this case, spaced notches a, the purpose of which will be described later. 4

It will be apparent that the seat a is rotatable upon the pedestal b and may be turned in either position depending upon the direction of travel of the vehicle.

Arcuate plates 6 are mounted on the upper portions of the standards 6 and b, and are adapted to engage the groove (1 when the seat is rotated into either of its normal positions. By means of this connection, the seat is supported directly upon the floor at its ends and the pedestal bearing is relieved of this function. In the standard I), a vertically movable pin 12 is carried, a spring Z) serving to urge thepin upwardly into engagement with either of the recesses (1 The standard I) is formed with an inwardly extending flange 6 upon which the spring 6 is seated, and on the inner side, a plate 6, formed with an arm 6 is secured to the standard. by means of bolts 6. A crank arm 0 is pivoted to the arm 6 and formed with a pedal portion 0' and an arm 0 engaging the pin 6 WVhen the pedal 0 is depressed, the arm 0 moves pin 6 downwardly against the action of spring 6 and permits rotation of the seat a, since the pin serves to hold the seat in either position. Arm 0 of lever a has secured thereto a link a carrying a yoke-shaped head 0 A longitudinally slidable member 03, carried in the side wall of housing I), is provided with a roller d adapted to engage notches a It will be apparent that the link a will disengage roller cl from the notches a and permit the roller to ride around the periphery of flanges a dropping into notches a when the seat has been rotated sufficiently. This serves as an automatic stop for positioning the seat correctly in either of its normal positions, and is connected with the latching means to permit them to function through a single manual operation.

It will be apparent that the specific construction and relation of elements may be changed and the arrangement of parts such as to provide varied forms of seats, and the invention is not to be limited, save as defined in the appended claim.

\Vhat I claim is:

In combination, end standards, a pedestal carried thereby, a seat, means to mount the seat rotatably on the pedestal, latching means carried at the ends of the seat, means on one of the standards to engage the latching means to hold the seat in a desired position, means pivoted to one of the standards to release the engaging means, a flange carried by the seat and movable with the seat, notches in the flange, a roller engaging the flange, and a link between the roller and pivoted member.

This specification signed this 14th day of July, A. D, 1927.
