Vehicle stopping and movement warning sensor
First Claim
1. A sensor (10) for actuating a vehicle warning signal, comprising:
- a housing (1);
a magnetically activated switch (5) located on an outside surface of the housing (1); and
an electrical connection (6) for connecting the switch (5) to a warning signal device (12) of the vehicle (9),the housing (1) comprisinga cavity (7) located inside the housing (1),a first spring (2) located inside the cavity (7), anda moveable magnetic weight element (3) located inside the cavity (7) adjacent the spring,wherein, in a first in-use condition the weight element is located in a first resting (P1), non-activating position remote from said switch (5),wherein, in a second in-use condition, during a deceleration of the vehicle, the weight element (3) moves to compress the first spring (2) so that the weight element (3) moves from the first position to a second activating position (P2) magnetically proximate the switch so that the switch is closed by magnetic interaction with the weight element (3), the closing of the switch causing the warning signal device (12) to be activated to provide a deceleration warning to following vehicles, andwherein, in normal driving of the vehicle, the first spring keeps the weight element (3) from moving to the second position proximate the switch.

Abstract
A sensor for actuating a vehicle warning signal includes a housing, a magnetically activated switch on an outside surface of the housing, and an electrical connection connecting the switch to a warning signaling device. The housing includes a cavity, at least one spring inside the cavity, and a moveable magnetic weight element adjacent the spring. In a first condition the weight element is located in a first resting, non-activating position remote from said switch, and in a second condition, during a deceleration of the vehicle, the weight element moves to compress the spring so that the weight element moves from the first position to a second activating position proximate the switch so that the switch is closed by magnetic interaction with the weight element, the closing of the switch causing the warning signaling device to be activated to provide a warning to following vehicles.

9. A sensor (10) for actuating a vehicle warning signal, comprising:
-
a housing (1);
first and second magnetically activated switches (5, 5′
) located on an outside surface of the housing (1); andelectrical connections (6, 6′
) for connecting the first and second switches (5, 5′
) to a warning signal device (12) of the vehicle (9),the housing (1) comprising a cavity (7) located inside the housing (1), first and second springs (2) located inside the cavity (7), and a moveable magnetic weight element (3) located inside the cavity (7) between the first and second springs, wherein, in a first in-use condition the weight element is located in a first resting, non-activating position magnetically remote from said first and second switches, wherein, in a second in-use condition, during a first movement of the vehicle, the weight element (3) moves to compress the first spring (2) so that the weight element (3) moves from the first position to a activating second position (P2) magnetically proximate the first switch so that the first switch is activated by magnetic interaction with the weight element (3), the activation of the first switch causing the warning signaling device (12) to be activated to provide a warning to following vehicles, wherein, in a third in-use condition the weight element (3) moves to compress the second spring (2′
) so that the weight element (3) moves from the first position to an activating third position (P2′
) proximate the second switch (5′
) so that the second switch (5′
) is activated by magnetic interaction with the weight element (3), the activation of the second switch (5′
) causing the warning signaling device (12) to be activated to provide a warning to following vehicles, and wherein, in normal driving of the vehicle, the first and second springs keep the weight element (3) from moving from the first position to either of the second and thirds position. - View Dependent Claims (10, 11)
