Abstract
A pedestal supports a base frame above which is a seat frame resiliently mounted on the base frame with four energy absorbing devices constituting the sole connection between the base frame and the seat frame. Each energy absorbing device comprises a block of rubber bonded to upper and lower metal plates extending from the block in opposite directions and connected by respective brackets to the seat frame and the base frame respectively. Each block has a bending or flexing surface inclined upwardly and outwardly toward the seat frame.
Claims9
In a seat:
- a base;
- a horizontally disposed seat frame having front and rear members each located above said base;
- front and rear energy absorbing means, cantilevered inwardly from said front and rear members of the seat frame, respectively, for resiliently mounting said respective front and rear members on said base;
- each of said energy absorbing means comprising a block of elastic, resilient material having upper and lower horizontal surfaces and parallel, inclined inner and outer surfaces extending upwardly from said lower surface in an outward direction relative to said seat frame;
- each inclined surface having a bottom edge at said lower horizontal surface and a top edge at said upper horizontal surface;
- top and bottom plates attached to said upper and lower horizontal block surfaces respectively;
- both of said inclined surfaces on each of said blocks being substantially totally exposed to facilitate unrestricted flexing thereof;
- each top plate comprising an end portion located outwardly of the top edge of said outer inclined block surface;
- means for connecting said end portion of said top plate of the front energy absorbing means to the front member of said seat frame;
- means for connecting said end portion of said top plate of the rear energy absorbing means to the rear member of said seat frame;
- and means for connecting the bottom plate of each of said energy absorbing means to said base.
