Definitions

• the invention relates to a safety seat for land, air and sea vehicles with a seat part, which is fixed to a vehicle-mounted and at least two vertical support members having scaffold.
• a safety seat with the aforementioned features is known from DE 102004062350 B3.
• the seat is fastened in each case to vertical between the vehicle roof and the vehicle floor clamped tethers by the seat shell is fixed by means of additionally arranged, connected to the vertical straps and with these a belt frame for holding the seat shell forming lateral straps on the vertical straps.
• the lateral support straps consist of one of a lower fixed attachment point along the side edges of the seat to the front corner points extending belt portion, each of the front corner points of the seat a further obliquely to the vertical axis of the vehicle seat extending belt portion to an upper stationary attachment point on the assigned vertical tether is returned.
• the seat is inserted into the belt frame formed of vertical tethers and straps so that the seat shell automatically tensions the belt frame.
• the disadvantage associated with the known safety seat is that when the seat part is loaded by a person seated thereon, the vertically mounted holding straps are loaded accordingly, so that the vehicle roof and the vehicle floor are stressed in the vertical "Z" axis, thus bending.
• the vehicles in question serve as troop transporters in which several persons are seated side by side in a row, considerable bending stress can occur in the associated roof area or floor area Due to the usually limited space, the arrangement of additional supports and / or roll bars for stiffening the vehicle structure is often not possible, but at least for the Fun hinders the vehicles.
• the invention is therefore the object of a safety seat with the generic features in such a way that with its attachment in the vehicle as low as possible force application in the form of bending forces or moments is connected to the vehicle structure.
• a further object is to be seen in designing the safety seat in such a way that the impulse forces occurring in the safety seat in the event of a thrown up of the vehicle during a mine launch or in the event of a crash with rolling over of the vehicle are at least reduced.
• the vertical holding elements each consist of a spring element which can be bent transversely to its longitudinal direction and is loosely set between the roof area and the floor of the vehicle, and in that the seat part has on its two sides, on the one hand, one end with its one end Fastened portion of the front edge of the seat part and obliquely to the longitudinal axis of the spring element in the direction of the roof area of the vehicle extending and fastened with its other end to a fixedly connected to the spring element fastening device tether and on the other hand via a fixed at one end in the rear edge of the seat part and guided in a direction rectified with the spring element course to the fastening device and secured thereto with its other end tether on the spring elements, being close to the arrangement of the fastening device between the tether and Fede Relement a spacer for the safety belt is arranged.
• the invention has the advantage that no fixed connection between the spring elements is provided as a carrier of the seat parts and the vehicle structure.
• a tension of the spring elements only occurs when a person sits on the seat part, it is at the then occurring forces introduced into the floor of the vehicle pressure forces, while on the vehicle roof at best in the roof plane, that is in "X" - or "Y" direction acting lateral support forces for the upper end of the spring elements are effective.
• the occurrence of bending forces is avoided especially in the roof area of the vehicle.
• the vehicle floor can be stressed in the direction of the "Z" axis with compressive forces rather than with the occurring according to the prior art, causing a bending stress Tensile forces.
• the spring elements holding the seat parts will damp the shocks resulting from any stress from the vehicle.
• the seat part is suspended by means of this supporting tethers and safety straps of the spring elements, so that thereby an effective decoupling of the seat part is given by the vehicle structure.
• the force at the position of the fastening device is introduced pointwise into the spring elements; also the forces absorbed by the straps under load of the seat part forces are introduced to the fastening device in the spring elements, which is ensured due to the substantially parallel course of safety strap and spring element by the arrangement of a spacer that the introduced from the safety belt in the associated spring element Forces have a component in the transverse direction of the spring element, so that in this way amplifies the force introduced by the tether and thus the spring element is subjected to bending in the manner of a strained bow.
• the spring elements are set loose with their ends in each case in the roof area and on the floor mounted brackets. This has the advantage that the spring elements can dodge when set in the manner of a strained bow in the load bending in the brackets.
• the spring elements are designed in the manner of a leaf spring, in particular as leaf spring packages.
• the number of combined to form a corresponding leaf spring package leaf springs whose thickness and width are dependent on the necessary length of the spring elements resulting from the respective requirements of the vehicle, its ceiling height and the possibilities of attachment.
• the spring elements consist of a spring steel.
• the fastening device is designed as a clamp.
• each of the trailing edge fixed in the region of the rear edge of the seat belt is designed in the manner of a loosely fitting loop part, this has the advantage that the seat part in the loop in a vertical position, can be folded up approximately parallel to the orientation of the spring elements.
• a catch strap and the spring element loose comprehensive consisting of a flexible material ring loop is provided.
• the safety seat is equipped with a safety harness for securing a seated occupant, according to one embodiment of the invention, the upper end of the shoulder belt or the shoulder straps on the Spring element or the spring elements is fixed and the ends of the lap belt are attached to the seat part.
• the safety seat is provided with a back support and / or with side supports.
• Fig. 1 a safety seat together with bracket in a schematic
• Fig. 2 shows the safety seat according to Figure 1 under load with a person sitting thereon.
• a spring element 12 is arranged between the roof area 10 and the floor 1 1 of a vehicle, which is loosely inserted with its two outer ends in a respective holder 13 arranged on the roof area 10 and the floor 11.
• the spring element In the unloaded state shown in FIG. 1, the spring element has a straight alignment.
• the spring element consists of a preferably formed from a plurality of leaf springs leaf spring package, wherein the individual leaf springs can be made of a conventional spring steel. Number of leaf springs, their thickness and ready are dependent on the length, which results from the respective requirements of the vehicle, its ceiling height and the possibilities of mounting the spring element.
• the seat part may consist of a fixed seat frame and a seat covering fixed to the frame, preferably of a textile material.
• the seat part 14 is fixed in each case on its two sides by a tether 15 on the associated spring element 12, which is struck with its one end to a arranged in the region of the front edge of the seat part attachment point 16; the other end of the obliquely to the longitudinal axis of the spring element 12 in the direction of the roof area 10 of the vehicle extending tether 15 by means of a fixed to the Spring element 12 connected fastening device 17 struck on the spring element 12. Since no bore is to be introduced into a corresponding spring steel, the fastening device 17 is preferably designed as a clamp or clamping device.
• a safety belt 18 which holds the seat part 14 in the region of its trailing edge with its one end placed in a loop 19 and in a rectified with the unloaded spring element 12 course up to the fastening device 17 and also thereon is attached.
• a spacer 20 is arranged in the immediate vicinity thereof, which ensures a distance between the gripping belt 1 8 and the spring element 12.
• a catch strap 18 and the spring element 12 loosely comprehensive ring loop 21, consisting of an elastic material provided.
• a safety harness which consists of one or two shoulder straps 22 fastened to the associated spring element 12 at 26, which are each adjustable in length by means of an adjusted adjustment device 25.
• a lap belt 23 is provided, whose both ends are respectively secured to the seat frame of the seat part 14; the lap belt 23 likewise has an adjusting device 25. Lap belt 23 and shoulder belt 22 and shoulder straps 22 are brought together in a central quick release closure 24.
• a loading of the seat part 14 with a person 30 seated thereon causes the entire force to be introduced via the tether 1 5 as well as the tether 1 8 into the fastening device 17, and as a result thereof bends the spring element 12 and the two bending a spring 14 supporting spring elements 12 in the manner indicated schematically in Figure 2 way through or out, so that a kind Arc voltage results.
• This deflection gives the existing of an elastic material loop 21.
• the suspension of the rear end of the seat part 14 in the loops 19 formed by the two-sided safety belts 18 makes it possible to fold the seat part 14 in the two loops 19 in a vertical position, thus a space-saving storage is realized.
