| 20120110800 | BUCKLE FOR RESTRAINT SYSTEMS FOR CAR SAFETY SEATS FOR CHILDREN, PROVIDED WITH A DEVICE FOR INDICATING THE CORRECT TENSIONING - A buckle includes a case connected to a restraint system lower belt. A coupling mechanism releasably engages tongue-like coupling elements connected to respective upper belts. An indicator indicates correct belt tensioning and has a visual symbol visible through openings in the case. The indicator moves in the case between a first position in which the visual symbol is not visible, for loose belts, and a second position in which the visual symbol is visible, for correctly tensioned belts. First springs urge the indicator towards the first position. A locking element in the case connects to an end of the lower belt. Second springs between the case and the locking element are resiliently deformed from tension on the lower belt. The locking element cooperates with the indicator so that when the indicator is in the second position, it is locked. | 05-10-2012 |
