Abstract: A safety seat 10, for use in a vehicle, where the safety seat 10 comprises a seat portion 19a, a backrest 19 having a head end remote from the seat portion 19a, a first and second mutually spaced anchorage locations 15 and 15a on the head end of the backrest 19, a connector 12 for engagement with a securement point on a vehicle, the connector 12 having a strap opening, a tether strap 11 extending in a loop from the first anchorage location 15, through the strap opening of the connector 12, to a second anchorage location 15a, and a length adjustor 13 or 13a for adjusting the length of the tether strap 11 loop. This provides a tether strap 11 suitable for use with the safety seat 10 in either a rear or forward facing position. Another significant advantage is having the adjuster 13 or 13a in line with the tether strap 11 to significantly reduce the effective length between the backrest 19 and the securement point on the vehicle.
