摘要:
A safety seat for land vehicles, aircraft or vessels, comprising a harness for suspension from fixed points of a vehicle and for supporting a vehicle occupant. Belt retractors are disposed at the fixed vehicle points, and fabric supporting belts extend from the harness to the retractors, which pretension the belts in a direction of retraction. A manually operable switching device allows the belt retractors to be switched into a free running state, a blocking state, or a positioning state. The free running state permits free withdrawal of the belts in a direction opposite to the pretension. The blocking state effects a complete blocking of the belts in both the withdrawal and the retraction directions. The positioning state effects blocking of the belts in only the withdrawal direction.

A land, air or sea vehicle having a transport compartment for accommodating cargo and/or seats and comprising at least one row of seats disposed next to one another in the longitudinal axis of the vehicle, and oriented transverse to the direction of movement of the vehicle, is provided in a central row of the transport compartment. Mesh frameworks of textile straps are suspended between roof and floor surfaces of the transport compartment and oppositely disposed side walls that extend in the direction of movement. Each seat is individually secured to one of the mesh frameworks which is secured, under tension, to the vehicle. Each mesh framework is comprised of two transverse straps and two vertical straps. The straps are spaced from one another by the width of the seat. The transverse straps are suspended between the side walls in the vicinity of the roof, and the vertical straps are suspended between the roof and floor. The transverse straps and the vertical straps are interconnected at their points of intersection.

A safety seat for land vehicles, aircraft and watercraft, including a sitting portion secured to two vertical support straps attached to a vehicle and disposed in the vicinity of the rear edge of the sitting portion. Each support strap is a strap sling stretched between vertically spaced-apart anchors on the vehicle and includes a front strap facing the seating portion and a rear strap spaced therefrom. A transverse rod near the rear sitting portion edge reaches into the intermediate space between front and rear straps and is secured in closed fixed loops situated on the rear straps. The sitting portion is braced against the strap slings via supports pivotably connected to side rods of the sitting portion and extending at an angle below the sitting portion to the straps slings. The supports, via a transverse bracing disposed at their lower ends, reach into the intermediate space between front and rear straps. This transverse bracing is supported in loose loops on the rear straps that permit vertical movement of the transverse bracing.

A textile belt strap, especially for use in personnel safety devices in land vehicles, aircraft and watercraft. At least one seam is provided on the belt strap for representation of loading of the belt strap that occurs. The seam extends in a longitudinal direction of the belt strap over a portion thereof, and is comprised of an upper thread disposed on one side of the belt strap and a lower thread disposed on the other side of the belt strap. Respective transverse seams are fixedly connected with the belt strap for delimiting opposite ends of the seam. An interlocking of the upper thread and the louver thread is provided externally of the belt strap such that either the upper thread or the lower thread has a linear length or extension between the transverse seams that delimit the seam.
摘要:
A seat for a land vehicle, aircraft, or watercraft, comprising a textile seat portion having a seating surface and a backrest with a supporting structure for the seat portion configured as a support frame extending about the seat portion. The support frame is in the form of a textile strap guided through vehicle-mounted eye rings. Portions of the strap extend laterally of the seat portion in the form of diagonal strap portions that each extend between one of the eye rings mounted below the seating surface and one of the eye rings mounted above the backrest. The seat portion is displaceably disposed on the diagonal strap portions. At least one adjustment strap is guided from the backrest to a fixation mechanism disposed above the seat portion.

A safety seat for land vehicles, aircraft and watercraft, including a seat portion, a backrest and side supports. A second backrest is disposed on the safety seat and is comprised of two backrest parts, the position of which relative to one another is adjustable to thereby achieve a varying spacing from the front edge of the seat portion. The backrest parts have a curved configuration to rest against a person seated on the seat, and outer side edges of the backrest parts are respectively attached to the side supports of the safety seat. An adjustment mechanism is provided for adjusting the position of the backrest parts.

A safety seat for land, air and sea vehicles is provided. The safety seat has a safety belt harness and can be secured between the floor and ceiling of a vehicle via securement straps provided above and below the seat. The safety belt harness comprises two lap belts and two shoulder belts that extend from the lap belts. Also provided is an activating device that, as an extension of the shoulder belts, is guided below a seat portion to the entry region thereof. A respective tensioning strap is yieldingly disposed between the shoulder belts and the front securement straps.
摘要:
For improving a method for rescuing a person sitting in an ejection seat that has ejected from an aircraft in an emergency, wherein depending on data collected by measuring apparatus arranged on the ejection seat a control device initiates deployment of stabilizing and/or braking parachutes attached to the seat and furthermore initiates separation of the person from the ejection seat, it is provided that while the connection between aircraft and ejection seat exists, current flight data for the aircraft are fed via a data bus to an ejection seat computer situated on the ejection seat and once the ejection seat has separated from the aircraft the movement data for the ejection seat in space are collected and forwarded to the ejection seat computer by a navigation platform attached to the ejection seat and, that the relevant flight data for the ejection seat are calculated in the ejection seat computer starting with flight position data for the aircraft at the time the ejection seat separated and when pre-established limits are met the stabilizing and/or braking parachutes are deployed and/or the seat/person separation is initiated.

In the quick-release lock for a parachute, a measuring device (1, 2) is used for continuously measuring the distance of the parachutist from the surface on which he intends to land. In this arrangement, the measured distance values are repeatedly compared with predetermined values in a comparing device (3, 4, 7) during the descent. Only if the measured values agree with the predetermined values during the last section of the descent during, which the comparisons are carried out, is the parachute automatically released from the load, for example a person, when the distance 0 is reached.
