Abstract
Abstract A floor structure of a car body, comprising a floor platereinforcing member which is fixed onto a floor plate and a tunnel portion and extends over a predetermined length. Even when an impact load is transmitted to a seat track through a seat belt, it is distributed over various parts, so that the deformation of the floor plate, etc. otherwise occurring is prevented.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
186 words
In an automobile having individually mounted seats and a drive shaft for transmitting power to wheels thereof, a floor construction for an automobile body, said floor construction comprising: a floor plate comprising, substantially along the centerline thereof, a substantially longitudinally extending substantially inverted U-shape tunnel portion adapted to partially surround the drive shaft, and a plate portion extending transversely from each lower edge of each side of the tunnel portion in a direction from the other side thereof, a substantially longitudinally extending reinforcing member mounted over the tunnel portion, said reinforcing member being connected to each plate portion and comprising attaching portions on each side threof adapted to have an inner seat track of a respective seat connected thereto, said reinforcing member, a longitudinally extending portion of each side of the tunnel portion, and a longitudinally extending portion of the respective plate portion extending from that side defining a respective substantially longitudinally extending air duct therebetween, an opening at one end of said ducts fluidly connected to the outlet of an air conditioner, and an air outlet at the other end of each of said ducts.
Claim 2
Dependent Claim
186 words
In an automobile having individually mounted seats and a drive shaft for transmitting power to wheels thereof, a floor construction for an automobile body, said floor construction comprising: a floor plate comprising, substantially along the centerline thereof, a substantially longitudinally extending substantially inverted U-shape tunnel portion adapted to partially surround the drive shaft, and a plate portion extending transversely from each lower edge of each side of the tunnel portion in a direction from the other side thereof, a substantially longitudinally extending reinforcing member mounted over the tunnel portion, said reinforcing member being connected to each plate portion and comprising attaching portions on each side threof adapted to have an inner seat track of a respective seat connected thereto, said reinforcing member, a longitudinally extending portion of each side of the tunnel portion, and a longitudinally extending portion of the respective plate portion extending from that side defining a respective substantially longitudinally extending air duct therebetween, an opening at one end of said ducts fluidly connected to the outlet of an air conditioner, and an air outlet at the other end of each of said ducts.
Claim 3
Dependent Claim
83 words
The floor construction for an automobile body as claimed in claim 1, wherein: an upper longitudinally extending portion of said reinforcing member is of a size and shape substantially identical to that of the upper portion of the U-shaped tunnel portion and is positioned thereon, said reinforcing member comprising a longitudinally extending flange extending transversely from each lower edge of each side of said reinforcing member, and securing means connecting each flange on each side directly to the plate portion on that side.
Claim 4
Dependent Claim
91 words
The floor construction for an automobile body as claimed in claim 1, wherein: the attaching portions converge together at said one end and define said opening, and the height, above the respective plate portion, of the portion of each of said attaching portions to which an inner seat track is adapted to be connected is substantially identical to the height, above the respective plate portion, of an outer seat track attaching portion on the respective side which is adapted to have an outer seat track of a respective seat connected thereto.
Claim 5
Dependent Claim
78 words
In an automobile having individually mounted seats and a drive shaft for transmitting power to wheels thereof, a floor construction for an automobile body, said floor construction comprising: a floor plate comprising, substantially along the centerline thereof, a substantially longitudinally extending inverted U-shaped tunnel portion adapted to partially surround a drive shaft, and a plate portion extending transversely from each lower edge of each side of the tunnel portion in a direction away from the other side thereof,
Claim 6
Dependent Claim
78 words
In an automobile having individually mounted seats and a drive shaft for transmitting power to wheels thereof, a floor construction for an automobile body, said floor construction comprising: a floor plate comprising, substantially along the centerline thereof, a substantially longitudinally extending inverted U-shaped tunnel portion adapted to partially surround a drive shaft, and a plate portion extending transversely from each lower edge of each side of the tunnel portion in a direction away from the other side thereof,
Claim 7
Dependent Claim
43 words
The floor construction for an automobile body as claimed in claim 4, wherein: said ducts coverge at one end and have an opening fluidly connected to a source of air, and and air outlet at the other end of each of said ducts.
Claim 8
Dependent Claim
41 words
The floor construction for an automobile body as claimed in claim 4, wherein: said reinforcing member further comprises a reinforcement plate integrally connected to each mounting portion adjacent points of attachment thereof of an inner seat track of a respective seat.
Claim 9
Dependent Claim
53 words
The floor construction for an automobile body as claimed in claim 4, wherein: said reinforcing member further comprises a horizontally extending flange portion extending transversely outwardly from the lower edge of each second wall portioN, and securing means connecting each flange portion on each side directly to the plate portion on that side.
