SEAT.

Application filed February 18, 1926. Serial No. 88,986.

This invention relates broadly to a seat or other weight supporting instrumentality for an occupant in either asitting or reclining position. More particularly the inyention relates to seats for passenger carrying vehicles. such as motor buses, and has for one of it object the provision of a seat or like support wherein a degree of freedom for movement is afforded in the interest of the comfort of the occupant. To this end the pedestal or support for the seat proper is so constructed and arranged as to provide for limited rocking movement of the seat in a fore and aft direction while rocking movement of the seat in a direction transvere thereto is constrained. A further object of the invention is the en hioning or ab orption of the shocks and vibrations ordinarily impressed on the seat from the vehicle body to prevent their transmission in whole or in part to the occupant. Accordingly the material of which the pedestal is formed 15 such as to cushion or absorb shock and vibration. More specifically, the pedestal is made of yielding non-metallic material, such as rubber. and. if desired, the material may be re-enforced or strengthened by cords or the like embedded therein. Still another aspect of the invention resides in the manner of securing the yielding non-metallic pedestal to the. fioor or other ba e. To this end the bottom surface of the pedestal is dished or made concave to serve as a suction cup whereby the pedetal is enabled to grip or adhere to the floor. These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description of the accompanying drawings illustrating a preferred embodiment iii which:

Figure 1 is a view in longitudinal vertical section showing the seat and pedestal according to the present invention.

Figure 2 is a view showing the seat in rear elevation and partly in transverse vertical section.

Figure 3 is a horizontal transverse sectional view of the pedestal taken in the plane indicated by the line 33 in Figure 2 and looking in the direction of the arrows and showing variations in the thickness of the walls whereby movement of the seat is per mitted in some directions and resisted in others.

While the invention has been illustrated and will be described in respect of a teat it is to be understood as applicable in any situation where a weight supporting instrumentality is required for an occupant in either a sitting or reclining position.

In the drawings the seat proper or supporting element which is indicated at a and comprises a rectangular frame a carrying a cushion support a and a back re:t,a 'is the points marked 0' in Figure 1 and Ont'he other handmovcment to the side. or sidesway. is undeirable and such movement is resisted by forming the walls at the sides relatively thicker. as at c in Figures Q and 3. The degree of movement. of course, is dependent upon features of dimension and compo ition. These relative dimensions are maintained in the pedestal up to the point of connection with the plate a of the supporting element. the top of the pedetal flaring to afford stability as shown and being reduced for clamping between the plate a and a ring 0* secured as by the bolts to the plate.

Downwardly from the flexing point the walls of the pedestal increase in diameter as at 0 also to add stability "to the structure although the relative proportions are maintained and inwardly the cylindrical recess 0* is terminated above the base to afford sufficientmaterial within which the suction cup 0 is formed whereby the pedestal is secured to the floor as will be understood. This suction cup is formed by dishing the lower face of the pedestal as shown in Figures 1 and 2 and the conically shaped walls and thickness of material below recess a are so proportioned as to give the required elasticity and resiliency to facilitate the function of the suction cup formed thereby. It, will thus be seen that a pedestal or base for a seat has been provided having inherent, in itself impositive means for securing it to a floor or support and capable of being readily secured to and. removed from the seat while the pedestal also has inherent in itself the capacity to permit a limited degree of rections and to resist movements in other directions.

It is to be understood thattthe invention in its broadest aspects is not to be limited to the use only in combination of all of the features hereinbefore enumerated but that certain features may be used either alone or in conjunction with others.

Furthermore various modifications in the application, form and composition of the pedestal and in the manner of securing the same either to the supporting element of the seat or to a base will occur to those skilled in the art and are to be deemed within the scope of the invention as defined in the appended claims.

lVhat I claim is:

1. In a seat, a. cylindrical pedestal formed of yielding non-metallic material whereof the walls vary in thickness in the same horizontal plane, whereby fiexion of the pedestal is permitted in a vertical plane and resisted' in a vertical plane perpendicularv thereto.

2. In a seat, the combination with a sup-' the cylindrical walls being of less diameter than the side portions, the walls of the pedestal increasing in thickness in a downward direction and means to secure the pedestal to a base.

3. In a seat, the combination with a supporting element and a base, of a edestal of yielding non-metallic materialo generally cylindrical form, the upper portion of the pedestals walls flaring, means to secure said flaring portion to the supporting element, the front and rear upper portions of the cylindrical walls being of less diameter than the side portions, the walls of the pedestal increasing in thickness in a downward direction and means dependent upon atmospheric pressure to secure the pedestal to a base.

4. In a seat, the combination with a supporting element, of a pedestal of yielding non-metallic material of generally cylindrical form and flaring at its upper end,

the walls of the pedestal being greater in thickness transversely and the lower portion of the pedestal being dished, and an annulus and bolts to clamp the flaring upper end to the supporting element.-

This specification signed this 8th day of February A. D. 1926.
