A VEHICLE SAFETY APPARATUS

摘要

A vehicle safety apparatus (1, 2) comprises an electronic sign (11), a registration plate support (21) covering the sign (11), a controller (2), and a mechanism (30) to, in response to an event, move the registration plate support (21) in a direction away from the sign (11) and up or down to expose the sign (11) and leave a registration plate (P) on the registration plate support (21) visible. The mechanism (30) has a rotating link (17, 18) at each lateral end of the registration plate support (21). The sign (11) is adapted to display any of a number of options and the controller (2) provides a default option. An in-car controller (2) comprises a radiation receiver and is adapted to respond to a remotely-transmitted signal to activate the warning sign. Also, the in-car controller (2) regularly polls the sign (11) and in absence of a response it generates a tampering output alarm.
