Abstract

A fastening device for a safety belt in motor vehicles comprises a guiding member to be mounted on the vehicle frame or on some other carrier in the vehicle in such a way that a clearance is created between the guiding member and the carrier and comprising also a runner, to which one end of the safety belt or corresponding organ is attached, and which may be displaced along the guiding member to be positioned in different positions, said positions being determined by a number of holes (40) or recesses disposed along the guiding member. The guiding member is a channel-shaped rail (30) with a web-section (39), which faces the clearance (39) and with side flanges (32) which first project from the web-section and then turn inwards towards each other. The in-turned parts (34) form between them a longitudinal channel (35) and are provided with said recesses or holes. The runner comprises both external parts (44) outside the rail and internal parts (45) essentially inside the rail, as well as connecting means (46) there between. The connecting means extent through the longitudinal channel of the rail. The external parts include a sleeve runner (44), enclosing entirely the rail. A back portion of the sleeve runner is positioned in the clearance between the rail and its carrier (36). The sleeve runner is provided with at least two holes (50) or a corresponding larger hole (50'), thus positioned that they/it may be placed above the holes or recesses of the rail. The internal parts include /a/ locking member/s/ (47, 47', 54, 65) arranged to enter simultaneously at least one of the holes or recesses in each of the two in-turned parts of the rail. The connecting means (46) comprises means to move said locking member/s/ inward and outward with respect to the said to release and engage, respectively, said locking member/s/ from and with, respectively, said recesses or hole/s/ of the rail as well as the hole/s/ of the sleeve runner positioned outside the rail.

Adjustable fastening device comprising a guide member mountable on a carrier so that a clearance is created between said guide member and said carrier, and a runner which may be displaced along said guide member and positioned in different positions, said positions being determined by a plurality of recesses disposed along said guide member, wherein said guide member is in the form of a rail comprising a web section, mountable adjacent said carrier and defining said clearance. and flanges extending firstly away from the web section and away from said carrier and then turning inwards toward each other, said in-turned portions between them forming a longitudinal channel, said in-turned portions each provided with said recesses;

said runner comprising both external parts outside the rail, internal parts essentially inside the rail and connecting means for operably connecting said external and internal parts;
said connecting means extending through said longitudinal channel of said rail;
said external parts including a sleeve runner, having a front portion and a back portion, enclosing entirely the rail, said back portion of said sleeve runner being positioned in said clearance between said rail and said carrier, said front portion of said sleeve runner provided with first means defining an aperture positioned such that said first aperture means may be placed above said recesses as of said rail;
said internal parts include locking means, being arranged to enter simultaneously at least one of said recesses in each of said in-turned portions of said rail, for locking said runner in a predetermined position on said rail;
and said connecting means includes movement means to move said locking means inward and outward to release and engage, respectively, said locking means from and with respectively, said recesses of said rail as well as said first aperture means of the sleeve runner positioned outside said rail;
and wherein said internal parts further comprise an interconnected member arranged within said channel of said rail, said interconnected member being rigidly connected to said front portion of said sleeve runner, said interconnected member having opposed edges extending, respectively, beneath said in-turned portions of said rail and said interconnected member is provided with second means defining an aperture, receivable of said locking means, aligned with said first means defining an aperture of said sleeve runner;
and said connecting means comprises a shaft, having a first end and a second end, connected to said locking means at said first end and to a push button at said second end, said push button being manually engageable to move said shaft, said shaft slidably extending through a first hole in said front portion of said sleeve runner and a second hole in said interconnected member.
