1. Height adjuster for safety belts in a vehicle comprising:
- a guide rail, U-shaped in cross-section, and having a central region and two outer sidewalls, the sidewalls and central region together defining an interior space, the guide rail being attachable to the vehicle, the guide rail further having an elongated opening in the central region and latch openings arranged in pairs along the central region, the central region further having inner sidewalls extending along respective side edges of the elongated opening, into the interior space, substantially parallel to the outer sidewalls such that the latch openings are disposed in the central region between the inner sidewalls and the outer sidewalls, the guide rail further having a second elongated opening, disposed on a side of the guide rail opposed to the elongated opening of the central region;
a pair of connecting bridges, each connecting bridge extending between the two outer sidewalls and across the elongated opening in the central region;
an adjustment carriage, displaceable in the interior space, along the guide rail and having a threaded bushing for receiving a return fixture;
an arresting mechanism for the adjusting carriage, constructed and arranged to be disposed in the adjustment carriage and to selectively engage the guide rail latch openings in a plurality of locking positions with respect to the guide rail; and
an elastic biasing member, constructed and arranged to bias the arresting mechanism towards the latch openings.
