Abstract
A seat back core for a vehicle having a fold down seat which is also required to serve as a load floor. The core is blow-molded and formed with a pair of parallel spaced walls having tying links extending between the walls to strengthen and rigidify the core but not to prevent flexure thereof. There is a peripheral closing wall around the core. An elongate metal member is incorporated into the core at the time that it is blow-molded and becomes a permanent part of the core. It serves to limit the flexure of the core, provide additional strength and may serve as an anchor for securement of hardware.
Claims12
A load floor for the core of a fold down vehicle seat or the like automotive structural member comprising
- A. a hollow blow-molded member of synthetic resin whose overall thickness is substantially less than its size and which is generally rectangular in configuration,
- B. including a pair of generally parallel walls extending over substantially all of said member and having a peripheral connecting wall joining them around the member,
- C. a plurality of tying links extending between the parallel walls on the interior of the member and comprising:
- i. each such link being integral with a first parallel wall and comprising an indented formation having a bottom which is generally parallel with said first parallel wall from which the indented formation extends,
- ii. the depth of the indented formation being such as to carry the said bottom into engagement with the interior surface of the second and opposite parallel wall and forming a web therewith which is approximately twice the thickness of either of the parallel walls,
- iii. the indented formation being produced during the blow-molding operation whereby the said bottom and the said portion of the respective parallel walls are permanently welded together,
- D. said tying links being distributed throughout the entire area of said member whereby to rigidify and strengthen said member throughout its area to serve as weight support,
- E. said member having means to accommodate if not enable securement of automotive hardware, and
- F. at least one of said indentations extending a substantial distance along the length of said load floor and having a channel shaped reenforcing member of metal locked to the bottom and sides thereof.
A load floor for the core of a fold down vehicle seat which comprises:
- A. a hollow blow-molded member of synthetic resin whose overall thickness is substantially less than its size and which is generally rectangular in configuration,
- B. including a pair of generally parallel walls extending over substantially all of said member and having a peripheral connecting wall joining them around the member,
- C. a plurality of indentations in at least one parallel wall spaced throughout the area of the member and each forming a tying link extending between the parallel walls, each tying link comprising the walls of the indentation and having the bottom of the indentation welded to the interior of the wall opposite that one from which it is indented,
- D. one indentation extending along the length of the member having a cross-section comprising a flat bottom and angled outward walls and
- E. a sheet metal reenforcing member of generally channel construction conforming to and locked into the bottom of the indentation and somewhat less than coextensive in length therewith.
