SEAT.

Application filed September 27, 1828. Serial No. 187,920.

The

fpresent invention relates to swivel seats 0 the type. adapted for use in motor where the seats may be rotated and secured to face in a plurality of directions.

An object of the present invention is to provide a swivel seat capable of being turned to a. plurality of positions and to devise an effective means to hold the seat against normal relative movements but to permit adjustment of the seat with ease.

Reference will now be had to the accompanying drawings for a more detailed description of the invention wherein:

Figure 1 is an elevation, in section, of one formof the invention.

Figure 2 is a plan View, partly in section, of the device of Figure 1, the section being on line 22 of Fi re 1.

Figure 3 is a etail view, partly in section, of the latch means and is taken on line 3-3 of Figure 2.

Figure 4 is a slightly modified form of the invention shown in Figures 1, 2 and 3.

In the drawings a is a base or pedestal which is formed with a vertical cylindrical portion a and a dog a The seat frame b has a downwardly extending shaft 12' which.

is received in the cylindrical portion a and a spring 0 and cap 0' serve as a thrust bearseat and occupant.

A flange b on shaft 6 has double cam surfaces 1) and b and between these cam portions are formed notchesb which are engaged by the dog a to hold the seat rection. The crest of each double cam porf tion is half wa between the two notches, so

that, should t e seat be pushed down and partially turned, upon re ieving the downward pressure the force of the spring in pushing the cam against the dog will turn the seat until the dog engages the nearest notch.

It is apparent that to reverse the position of the seat it is necessary only to push the seat down and rotate it sufiiciently to engage the cam under the dog. Further turning of the seat until the dog has passed over the ridge of the cam results in the dog sl ppmg into place under the force exerted by the spring on the seat.

Figure 4 illustrates a form in which the bot-tom b of the seat frame is mounted on a pedestal or shaft 6 which rests directly on the floor. The back and arm of the seat are unitary and independent ofthe seat and are indicated at d'. Formed on the bottom of this unitary structure is a sleeve d which fits over the shaft 6.

The flange and latch means is formed .on th s sleeve and a spring 0 serves to actuate the latching device as in the previously described construction. The advantage of this form is that the-arms only need be depressed to reverse the seat, and since normally but sl1gh t pressure is placed upon the arms, a relat1ve1y light spring may be used for the thrust bearing. y

Qther modifications may be designed which fall within the sco e of this invent1on and it is not to be limited except as defined in the appended claim.

What I claim is:

In a seat wherein the seat frame is supported in the base with capability for relative movementsfi a base, a seat frame mounted therein, a ange on the seat frame, a plurality of double cam faces carried by the flange, notches between the cam faces, a dog carried .by the base and a s ring resisting downward movement of t e frame to engage the dog with the notches and cam aces. v I

This specification signed this 23rd day of September A. D. 1926.
