Abstract: A vehicle seat for absorbing energy exerted on the seat during impact including a seat frame having at least one generally vertical segment, a support apparatus including at least one generally vertical pole and at least one coupler fixedly mounted on the at least one pole of the support apparatus and circumferentially mounted on the at least one generally vertical segment of the seat frame, the at least one coupler having at least one deformation member engaging an indentation in the at least one segment such that displacement of the seat frame relative to the support apparatus occurs only when the force of the impact acting on the seat frame exceeds a preselected threshold.

Abstract: Mine clearing apparatus for attachment to a vehicle and comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation; apparatus mounted onto the frame for raising and shunting aside mines including a plow section, the plow section defining a plurality of plow teeth which, in operation, extend below the ground surface, and conveyer apparatus extending along the length of the plow section and adapted to convey the contents of the earth raised by the plow section to one side of the vehicle.

Abstract: Mine clearing apparatus for attachment to a vehicle and comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation; apparatus mounted onto the frame for raising and shunting aside mines; and apparatus operable from inside the vehicle for automatically raising the plow from its lowered orientation to its raised orientation independently of vehicle movement. The frame may include angled side portions mountable onto the vehicle and having a profile complementary to that of the vehicle and the apparatus for raising and shunting aside mines includes a pair of angled arms having a profile complementary to that of the frame and the vehicle.

Abstract: Mine clearing apparatus for attachment to a vehicle and comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation; apparatus mounted onto the frame for raising and shunting aside mines; and apparatus operable from inside the vehicle for automatically raising the plow from its lowered orientation to its raised orientation.

Abstract: Mine clearing equipment mountable on a vehicle. Two plow sections arranged one above the other in hinged engagement are included in apparatus which mounts on a frame and by which mines are raised and shunted aside. The frame in turn is mountable onto the vehicle in raised or lowered orientation. In the frame raised position, the plow sections are in folded engagement. The raising and shunting aside apparatus is angularly oriented with a forward edge adjacent the vehicle interior and a rearward edge adjacent the vehicle side edge. A chain is attached to the forward edges and plow sections in tension when the plow sections are lowered into their operating orientations to define mine barriers.

Abstract: Apparatus for clearing mines comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation, plow apparatus for raising and shunting aside mines mounted onto the frame and apparatus for automatically raising the plow from its lowered orientation to its raised orientation in response to backwards motion of the vehicle and including mounting apparatus rotatably mounted onto the vehicle, spring supporting apparatus mounted onto the mounting apparatus and attached to the plow apparatus; and tooth apparatus fixed onto the mounting apparatus and arranged for selectable engagement with a vehicle tread, the spring supporting apparatus being operative when the plow is in its lowered orientation to urge the tooth apparatus into driven engagement with the vehicle tread whereby during backwards movement of the vehicle the mounting apparatus rotates in a first direction, thereby extending the length of the spring supporting apparatus, and increasing the spring force thereof until

Abstract: Mine clearing apparatus for attachment to a vehicle comprising a frame mountable onto a vehicle for selectable positioning in a raised or lowered orientation; apparatus for raising and shunting aside mines mounted onto the frame; and apparatus for selectably retaining the frame in a raised orientation and comprising control apparatus operable from inside the vehicle for releasing the frame from the raised orientation and allowing it to assume the lowered orientation.
