Floor assembly for motor vehicles

Claim 2

A floor assembly for motor vehicles comprising a skeleton frame having a base frame and inner longitudinal supports, said base frame having transverse supports and lateral longitudinal supports, all of said supports being firmly attached to each other without the aid of plastic material, and a layer of plastic material tightly covering each of said supports while leaving predetermined portions of said supports uncovered to facilitate installation of various motor vehicle elements, said plastic material also being disposed in sheet form horizontally between said supports to serve as the only floor for the assembly, said plastic material covering said supports and said plastic floor being a single integrally formed member.

Claim 3

A floor assembly for motor vehicles comprising a skeleton frame including a base frame, longitudinal and transverse supports and wheel box supports, all of said supports being firmly attached to each other without the aid of plastic material, and a layer of plastic material tightly covering each of said supPorts while leaving predetermined portions of said supports uncovered to facilitate installation of various motor vehicle elements and tightly covering each of said wheel box supports, said plastic material also being disposed in sheet form over the wheel box supports so as to form wheel boxes and horizontally between said supports to serve as a single floor for the assembly.

Claim 4

A floor assembly for motor vehicles comprising a skeleton frame including a base frame, longitudinal and transverse supports and wheel box supports, all of said supports being firmly attached to each other without the aid of plastic material, and a layer of plastic material tightly covering each of said supPorts while leaving predetermined portions of said supports uncovered to facilitate installation of various motor vehicle elements and tightly covering each of said wheel box supports, said plastic material also being disposed in sheet form over the wheel box supports so as to form wheel boxes and horizontally between said supports to serve as a single floor for the assembly.

Claim 5

The floor assembly according to claim 2 wherein said wheel box supports include a pair of front and a pair of rear wheel box supports, each of said front wheel box supports forming a downwardly open arc, said base frame including lateral longitudinal supports and said skeleton frame including inner longitudinal supports having front and rear ends extending outwardly of the front and rear ends of said lateral longitudinal supports, respectively, an end of each said downwardly extending arc being disposed near said outward end of each said inner longitudinal support and another end of each said downwardly extending arc being disposed near said front end of each said lateral longitudinal support, and each of said inner longitudinal supports having a knee portion located near said front end to permit said inner longitudinal supports to bend and thereby absorb the force of impact in the event of a collision.

Claim 6

The floor assembly according to claim 2 wherein each of said supports consist of sheet metal stampings formed in the shape of box beams, said box beams having sides that are curved to resist the pressure of said plastic floor.

Claim 7

The floor assembly according to claim 2 wherein the skeleton frame also includes inner longitudinal supports, the opposite ends of a pair of said inner longitudinal supports extend outwardly beyond the front and rear ends of said base frame, the outer ends of said inner longitudinal supports being hook-shaped and including said predetermined portions uncovered by said plastic material.

Claim 8

The floor assembly according to claim 5 wherein said hook-shaped ends of said inner longitudinal supports are removably mounted thereon.
