Abstract
A seat belt tension sensing device adapted for sensing tension in a belt securing a child's car seat in a vehicle, and comprising a housing (52) having a upper housing member (50) hingedly attached (at 54) to a lower housing member 52, and a closure catch (58) to permit the passage of a length of seat belt (36) through the housing to pass over a depressible switch (66). Within the housing is a power source (40) and alarm/indicator (41) responsive to a signal emitted by the switch (66) when actuated by the scar belt (36) passing over the switch. Sufficient belt tension may be shown by a visible indicator, while insufficient tension may be indicated by an audible alarm.
