Means for releasably anchoring vehicle seats
SUMMARY OF THE INVENTION 
     This invention relates to devices for securing vehicle seats to the floor and has special application to releasable devices of this type. 
     Usage of a vehicle, such as a van, for the purpose of hauling cargo often requires the removal of the vehicle rear seats. To facilitate the removal and installation of the seats quick release brackets have been developed such as the one shown in my U.S. Pat. No. 4,595,164. 
     One problem with such brackets is the lack of space between the seat cushion and the lower frame tube which restricts the use of previous fasteners. The bracket of this invention includes an angularly oriented fastener and anchor part to fit into the small space between the seat cushion and frame tube. 
     Accordingly, it is an object of this invention to provide a quick release seat bracket which facilitates rapid installation and removal of vehicle seats. 
     Another object of this invention is to provide for a quick release bracket which is operable in confined and limited areas. 
     Another object of this invention is to provide for a quick release bracket which is usable with flat top seat frame support rails. 
     Other objects of this invention will become apparent upon a reading of the following description.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described to illustrate the principles of the invention, and its application and practical use to thereby enable others skilled in the art to utilize the invention. 
     Referring now to the drawings, reference numeral 10 refers generally to a vehicle seat which includes lower U-shaped tubular frame supports 12, 14. Seat 10 is generally employed in a vehicle (not shown) such as a van or similar vehicle which may be used both to haul cargo van/or transport passengers. 
     Reference numeral 16 refers generally to the support rails which support seat 10 above the floor 20 of the vehicle (not shown). Rails 16 are shown in detail in FIGS. 2-3 and include a  base 18 which is secured to vehicle floor 20 by fasteners 22 as shown in FIG. 3. Rails 16 also include raised spaced support parts 24 which are generally T-shaped in cross-sectional configuration as shown in FIG. 3 and separated by a gap 26. As shown, each support 24 includes spaced vertical legs 27, 28 and an integral connected support shelf 30 which has a substantially flat upper surface 32. Each support part 24 also includes depending marginal flanges 34 which run for substantially the entire length of each support part. 
     Reference numeral 36 refers generally to the anchor member which houses the frame supports 12, 14. Each anchor member 36 includes an elongated channel part 38 which defines channel 40 to house frame support 12 or 14. The exact configuration of channel part 38 is not critical except that the top walls 42, 44 should preferably be oriented at an oblique angle with respect to surface 32 if there is little space between the seat cushion 11 and the top walls for inserting the fasteners 46. Each anchor member also includes lower opposed downwardly and inwardly extending integral flanges 48 with an upwardly projecting flange 52 extending therefrom. 
     As shown in FIG. 2, each support 24 is interrupted at a central portion thereof, to allow the individual fasteners 36 to be installed and slid over the supports after seat frame supports 12 and 14 have been placed atop the upper surface 32. The method of installing anchors 36 is more clearly defined in my U.S. Pat. No. 4,595,164, which is incorporated herein by reference. 
     Seat 10 is installed and secured to support rails 16 as follows. With the frame supports 12, 14 resting atop rails 16 anchor member 36 is positioned over gap 26 as shown in FIG. 2, and lowered until one of the frame supports is enclosed in channel part 38. Anchor member 36 is then slid over rails 16 with flanges 52 locked against transverse sliding by depending flanges 34 as shown in FIG. 3. Fastener 46 depicted as a thumb screw and wing nut combination is then turned through top wall 42 into bearing contact with support member 12 or 14 to secure the support to rails 16 as shown. Decorative cover 56 may then be snapped over rails 16 as shown in FIG. 4 to provide a finished aesthetic look. To remove the seat 10 for cargo hauling the above procedure is reversed. 
     It is understood that the invention is not limited to the above details, but may be modified within the scope of the following claims.
