An electronic parachute deployment system includes an electronic actuator, a control module, a deployment actuator, and a release mechanism. A parachute is positioned on a payload device, such as a racecar, to slow or stop the payload upon receipt of an electronic deployment activation signal. The electronic deployment signal is verified, including determining proper voltage and source. The deployment system includes multiple redundancies including mechanical deployment redundancy, remote deployment redundancy, and power supply redundancy. The control module responsible for monitoring deployment includes indicators and sensors to indicate a status, operation, or mode relative to the operability of the payload device, relative to components of the release mechanism, and relative to the parachute deployment.

A head and neck support and protection device includes an arm that is pivotably mounted, at a first end, to a support and has at a second end a slidably-mounted element connected to a helmet clip. The helmet clip engages a helmet pin. A resistance block transfers energy into a vehicle chassis when the arm hits the resistance block. The slidably-mounted element slides out of the arm, in a controlled manner, when conditions indicating a crash have been met.

A kart includes a frame, front and rear wheels rotatable about front and rear axle axes, and an impact protection structure surrounding the frame. The impact protection structure includes: at least one front protective element, at least one rear protective element, and at least one lateral protective element on each lateral side of the kart. Each of the at least one lateral protective element is mounted to a pivot bearing fixed to the frame so as to be pivotally adjustable about a frame vertical axis, and is disposed closer to the rear axle axis than to the front axle axis. Each of the pivot bearings includes a bearing block and a bearing pedestal pivotable relative to the bearing block. Each of the at least one lateral protective element engages the bearing pedestal of a corresponding pivot bearing. Shock-absorbing dampers are disposed between the frame and the protective elements.

A head and neck restraint device for high performance race car drivers. The device includes a yoke, a collar and a pair of legs. The yoke and/or collar are adapted to pivotably articulate with respect to the legs. At least a portion of each leg can flex in response to force.

A head and neck support and protection device, which has an arm that is pivotably mounted, at its first end, to a support. At its second end, the arm has slidably-mounted element connected to a helmet clip for engaging a helmet pin. The device further includes a resistance block for transfering energy into a chassis when the arm hits the resistance block. The slidably-mounted element slides out of the arm, in a controlled manner, when conditions indicating a crash have been met. A protective pin is positioned in the arm and in the slidably-mounted element and configured to be cut by a force acting on the slidably-mounted element during a crash.

A locking clip and anchor assembly for a tether. The clip includes an opening with at least one tab extending into a portion of the opening. The clip is also configured to attach to a tether or strap. In exemplary embodiments, the anchor assembly includes a post, biased support, biasing mechanism, and base. The clip is configured to be connectable to the post and movable to latched and unlatched conditions with respect to the anchor assembly. In the latched condition the clip has a limited range of rotation possible about the post.
