Abstract

A safety seat with a safety belt, in particular for motor vehicles, with a seat and backrest frame, the backrest frame being adjustable in rake about a pivot axis and being supported on the seat frame through adjustable diagonal braces, the terminal points of a three-point safety belt being attached to the seat and backrest frame.

Claims

1. A safety seat with a three-point safety belt, in particular for motor vehicles, the seat having seat and baCkrest frames, pivot means supporting the backrest frame for rake adjustment about a pivot axis, and at least one adjustable diagonal brace extending between the seat frame and backrest frame controlling the rake adjustment, characterized in that a production backrest frame is constructed and arranged to be forwardly pivotable relative to a seat frame, the backrest frame being pivotally supported for swinging movement about a lower pivot axis into a position facilitating entry to the vehicle compartment to the rear thereof, the pivot means supporting the backrest frame for rake adjustment providing an upper pivot axis, the adjustable diagonal rake controlling brace being attached to the seat frame at the lower pivot axis and to the backrest above the upper pivot axis, the seat frame being provided on at least one side with attachment points receiving bolts, safety rails attached by the bolts to the seat frame, the safety rails being positioned in parallel relationship to fore and aft seat slide rails, safety profiles anchored to the vehicle body, i.e., the drive shaft tunnel and the door sill, receiving the safety rails, the safety rails have substantially frictionless contact with the safety profiles, the bottom terminal points of the three point safety belt being attached to the safety rails through the seat frame and the top terminal point to the backrest frame, and the safety rails engaging in interlocking fashion in the safety profiles when tilted as a consequence of high deceleration forces.

2. A safety seat as claimed in claim 1, characterized in that the safety rails have a box section with flanges and the safety profiles a channel section which is open laterally towards the seat.

3. A safety seat as claimed in claim 2, characterized in that the safety profiles are attached directly to a height adjustment mechanism in the event that the vehicle seat has height adjustment, and are pivotable through the medium of slotted holes on bolts attached to the transmission tunnel and the door sill.

4. A safety seat as claimed in claim 3, characterized in that the upper terminal point of the safety belt is preferably constituted by an eye on the backrest frame in the neighborhood of the headrest, from which the safety belt extends downwards to a reel-in device secured to the safety rail.

5. A safety seat as claimed in claim 4, characterized in that the safety belt can be pivoted forwards in the neighborhood of its top terminal point through the medium of a lever arrangement mounted on the backrest frame.

6. A safety seat as claimed in claim 5, characterized in that the lever arrangement consists of a first lever connected by a shaft to the pivoting wheel, to the end of which first lever one end of a compression spring is attached whose other end engages a second lever which can be pivoted past the dead center position of the compression spring by means of an electromagnet.

7. A safety seat as claimed in claim 1, characterized in that the upper terminal point of the safety belt is preferably constituted by an eye on the backrest frame in the neighborhood of the headrest, from which the safety belt extends downwards to a reel-in device secured to the safety rail.

8. A safety seat as claimed in claim 7, characterized in that the safety belt can be pivoted forwards in the neighborhood of its top terminal point through the medium of a lever arrangement mounted on the backrest frame.

9. A safety seat as claimed in claim 8, characterized in that the lever arrangement consists of a first lever connected by a shaft to the pivoting wheel, to the end of which first lever one end of a compression spring is attached whose other end engages a second lever which can be pivoted past the dead center position of the compression spring by means of an electromagnet.

10. A safety seat as claimed in claim 1, characterized in that the safety belt can be pivoted forwarDs in the neighborhood of its top terminal point through the medium of a lever arrangement mounted on the backrest frame.

11. A safety seat as claimed in claim 10, characterized in that the lever arrangement consists of a first lever connected by a shaft to the pivoting wheel, to the end of which first lever one end of a compression spring is attached whose other end engages a second lever which can be pivoted past the dead center position of the compression spring by means of an electromagnet.
