Abstract
A seat slide device for adjusting the forward and backward positions of the seat which comprises an upper rail and a lower rail, the upper rail being slidably fitted to the lower rail, in which a seat belt is at its one end secured to one of the upper rail and seat. In one of the upper and lower rails, formed are a plurality of projected pieces, while in the other of those rails, formed are a plurality of incised portions, so that, when an upward pulling force is exerted upon the upper rail via the seat belt, the projected pieces are pressed against the incised portions to bend them and pass therethrough, thereby causing a mutual direct engagement of the upper and lower rails to prevent removal of the upper rail from the lower rail.
Claims11
A seat slide device having an upper rail to be fixed to a floor of an automobile and a lower rail to be fixed to the side of a seat, said upper rail being slideably fitted to said lower rail, wherein a seat belt is provided on one of said seat or upper rail, said seat slide device comprising:
- a plurality of easily bendable incised portions formed in said upper rail such that they are spaced apart from one another at a predetermined interval and until bent, said incised portions lying in the same plane as adjacent portions of said upper rail and forming a substantially unperforated surface with said adjacent portions;
- and
- a plurality of projected pieces formed in said lower rail, said projected pieces being so arranged that they are disposed at points corresponding to the respective said incised portions;
- whereby, when an upward pulling force is exerted upon said upper rail, causing said upper rail to move upwards, said projected pieces of said lower rail are pressed against, and strongly gripped by engagement with said incised portions of said upper rail to bend said incised portions and pass therethrough, so as to effect a mutual engagement of said upper and lower rails, which prevents removal of said upper rail from said lower rail.
A seat slide device having an upper rail to be fixed to a floor of an automobile and a lower rail to be fixed to the side of a seat, said upper rail being slidably fitted to said lower rail, wherein the seat belt is proivided on one of said seat or upper rail, said seat slide device comprising;
- a plurality of projected pieces formed in said upper rail such that they are spaced apart from one another at a predetermined interval;
- and
- a plurality of easily bendable insized portions formed in said lower rail, said insized portions being so arranged that they are disposed at points corresponding to the respective said projected pieces and until bent, said incised portions lying in the same plane as adjacent portions of said lower rail and forming a substantially unperforated surface with said adjacent portions;
- whereby, when an upward pulling force is exerted upon said upper rail, causing said upper rail to move upwards, said projected pieces of said upper rail are pressed against, and strongly gripped by engagement with said incised portions of said lower rail to bend said incised portions and pass therethrough, so as to effect a mutual engagement of said upper and lower rails, which prevents removal of said upper rail from said lower rail.
