Abstract
Abstract A seat adjuster in which a seat frame supporting a seat body is provided with a pair of flanges extending inwardly from the opposite side walls thereof, and a channel of suitable sectional shape is formed on each of these flanges to slidably receive therein a bar of complementary sectional shape supported on the floor surface of a vehicle so that the seat frame can make sliding movement along the bars. This seat adjuster can be mounted without requiring any substantial space between the seat frame and the floor surface.

Claim 1
Independent Claim
130 words
A seat adjuster for use in a vehicle or the like comprising a pair of bars supported in parallel with each other on the floor surface of the vehicle, a seat frame supporting a seat body thereon and including a pair of opposite vertical side walls each having a substantially horizontal flange formed integrally therewith extending inwardly therefrom, said flanges extending the depth of the seat, and bar engaging means formed on each of said flanges, said bar engaging means having a sectional shape complementary to the sectional shape of at least a portion of each said bar, said bar engaging means engaging with said bars for allowing free sliding movement of said seat frame on said bars so that said seat frame can make sliding movement along said bars.
Claim 2
Dependent Claim
130 words
A seat adjuster for use in a vehicle or the like comprising a pair of bars supported in parallel with each other on the floor surface of the vehicle, a seat frame supporting a seat body thereon and including a pair of opposite vertical side walls each having a substantially horizontal flange formed integrally therewith extending inwardly therefrom, said flanges extending the depth of the seat, and bar engaging means formed on each of said flanges, said bar engaging means having a sectional shape complementary to the sectional shape of at least a portion of each said bar, said bar engaging means engaging with said bars for allowing free sliding movement of said seat frame on said bars so that said seat frame can make sliding movement along said bars.
Claim 3
Dependent Claim
62 words
A seat adjuster as claimed in claim 1, wherein said bar engaging means comprises channel means formed integrally with said flanges by bending a portion of said flanges to a shape for slidably receiving therein said bars so that said seat frame slides along said bars, said bar engaging means extending the depth of the seat for elongate engagement with said bars.
Claim 4
Dependent Claim
64 words
A seat adjuster as claimed in claim 2 wherein said channel means extend upwardly and have a semicircular sectional shape, and said bar engaging means include a reenforcing member having a downwardly extending semicircular channel formed therein to form a channel of circular shape in section with said channel means to receive a bar and retain the seat against both upward and downward movement.
Claim 5
Dependent Claim
60 words
A seat adjuster as claimed in claim 1 further comprising reinforcing means having a sectional shape complementary to the sectional shape of another portion of said bars, said reinforcing means being secured to said bar engaging means to define therebetween a space for slidably receiving therein said bars so that said seat frame can make sliding movement along said bars.
Claim 6
Dependent Claim
45 words
A seat adjuster as claimed in claim 1, wherein said bar engaging means comprises channel means formed by upwardly and downwardly curving alternate portions of said flanges for slidably receiving therein said bars so that said seat frame can make sliding movement along said bars.
