Description

A SEAT FOR ABSORBING A FORCE
This invention relates to a seat and, more especially, this invention relates to a seat for absorbing a force. The seat may absorb a force from, for example, a blast from a mine, or a crash from an aeroplane or a helicopter.
Vehicles travelling in areas of conflict throughout the world are often subject to mine blasts. The conflicts may be wars or simply acts of terrorism. The vehicles may be military vehicles or civilian vehicles. The mines may be properly constructed mines of the type used by armies, or the mines may be improvised explosive devices of the type used by terrorists. Irrespective of the type of vehicle or the type of mine, people travelling in vehicles which are blown up by mines often suffer loss of life or severe injuries including loss of limbs and/or spinal damage. An initial blast from a mine will act upwardly and may blow a vehicle upwardly and into the air. A second damaging force acts downwardly and occurs when the vehicle strikes the ground after having been blown upwardly into the air. This second force is sometimes referred to as a slam-down force.
Aeroplanes and helicopters rarely crash, but nevertheless crashes do happen. The downward force during a crash is usually substantial but there are occurrences, especially with helicopters, when the downward force is not so great that all occupants are killed. In this case, the occupants may suffer serious injuries due to the downward force of the crash. It is an aim of the present invention to reduce the above mentioned problems.
Accordingly, in one non-limiting embodiment of the present invention there is provided a seat for absorbing a force, which seat comprises a seat portion, a backrest portion, and a hinge arrangement which connects the backrest portion to the seat portion, and the hinge arrangement being a sacrificial hinge arrangement which is configured to collapse consequent upon the seat receiving the force and thereby to absorb at least a part of the force.
The seat of the present invention is advantageous in helping to prevent the above mentioned injuries and in particular the spinal injuries.
Preferably, the sacrificial hinge arrangement is configured to collapse progressively consequent upon receiving the force.
Preferably, the sacrificial hinge arrangement is configured to collapse in a downward direction. This enables the sacrificial hinge to operate when a vehicle blown up by a mine returns to the ground and strikes the ground. Alternatively or additionally, the sacrificial hinge could operate consequent upon receiving the initial blast from a mine which acts to force the vehicle upwardly into the air. With aeroplanes, helicopters and other crashes, the sacrificial hinge arrangement will normally collapse on impact with the ground.
The sacrificial hinge arrangement may comprise a pivot and a series of deformable slots. Other types of sacrificial hinge arrangement may be employed. The deformable slots may be decrease in size as they get further away from the pivot. Other slot arrangements may be employed. Preferably, the deformable slots are curved. Straight slots may however be employed.
The seat may be in one in which each one of the deformable slots extends sideways with respect to a frame part of the backrest portion, and in which all the deformable slots form a series of deformable slots extending in a longitudinal direction along the frame part. Other deformable slot configurations may be employed.
The seat may be one in which the seat portion comprises a first recessed area for receiving a person's buttocks, and a pair of second recessed areas for receiving a part of the person's legs underneath their thighs.
The first recessed area may comprises two recessed portions, one for each buttock. The two recessed portions may be joined to each other, or they may be separate from each other.
The seat portion may be a hard seat portion made of a hard material. The hard material may be a metal, for example the same as is used for the rest of the seat or for a part of the seat. Alternatively, the seat portion may be a soft seat portion made of one or more foam materials.
The present invention also provides a vehicle when provided with the seat.
The vehicle may be a military vehicle such for example as an all terrain vehicle, a lorry, a personnel carrier to a tank. Alternatively, the vehicle may be a civilian vehicle, for example a bus, coach, taxi or car. Alternatively, the vehicle may be an aircraft such for example as an aeroplane or a helicopter.
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which:
Figure 1 is a side view of a first seat for absorbing force from a blast from a mine;
Figure 2 is an enlarged view of a hinge arrangement used in the seat shown in Figure 1 ;
Figure 3 is a section on the line X - X shown in Figure 2;
Figure 4 shows part of a second seat for absorbing force from a blast from a mine;
Figure 5 is a view like Figure 1 but shows a first alternative hinge arrangement to that shown in Figure 2; and
Figure 6 is a view like Figure 2 but shows a second alternative hinge arrangement to that shown in Figure 2.
Referring to Figures 1 , 2 and 3, there is shown a seat 2 for absorbing force from a blast from a mine. The seat 2 comprises a seat portion 4, a backrest portion 6 and a hinge arrangement 8. The hinge arrangement 8 connects the backrest portion 6 to the seat portion 4. The hinge arrangement 8 is a sacrificial hinge arrangement 8 which is configured to collapse consequent upon the blast from a mine and thereby to absorb force from the blast from the mine.
The sacrificial hinge arrangement 8 is configured to collapse progressively consequent upon receiving the force from the blast from the mine. More specifically, the sacrificial hinge arrangement 8 is configured to collapse in a downward direction. If a vehicle containing the seat 2 is blown up by a mine, then there will be an initial upward force shown by an arrow 10 which will tend to blow the vehicle, and therefore the seat 2, into the air. There will then be a downward force shown by an arrow 12 which will occur when the vehicle, and therefore the seat 2, hit the ground. When the vehicle, and therefore the seat 2, hit the ground, a person 14 sitting in the seat 2 is most likely to become killed or injured. If the vehicle and/or the seat are very well constructed and/or the blast from the mine is not too great, then the person may not suffer loss of life or loss of limbs. There is however a substantial chance that the person 14 will suffer spinal injuries. The sacrificial hinge arrangement 8 is especially useful in helping to prevent these spinal injuries.
The sacrificial hinge arrangement 8 comprises a pivot 16 and a series of deformable slots 18. As shown in Figures 1 and 2, the deformable slots 18 decrease in size as they get further away from the pivot 16. The deformable slots 18 are curved. As best appreciated from Figure 2, each one of the deformable slots 18 extends sideways with respect to a frame part 20 of the backrest portion 6. All the deformable slots 18 form a series of deformable slots 18 extending in a longitudinal direction along the frame part 20.
Referring now to Figure 4, there is shown a part 22 of an alternative seat portion for a seat. The part 22 is a part of the seat portion that is sat on and it has a first recessed area 24 for receiving a person's buttocks, and a pair of second recessed areas 26 for receiving a part 28 of the person's legs 30 underneath their thighs 32. The first recessed area 24 comprises two recessed portion 34, one for each of the person's buttocks. The two recessed portions 34 are connected together by a recessed portion 36. The part 22 may be a hard part made of a hard material, or it may be a soft part made of one or more foam materials.
Referring now to Figure 5, there is shown a sacrificial hinge arrangement 38 which has deformable slots 14 arranged vertically rather than horizontally as shown in Figure 2.
Referring to Figure 6, there is shown a sacrificial hinge arrangement 42 having deformable slots 44 which extend generally horizontally and which are provided both above and below the pivot 16.
The seat of the present invention enables the seat architecture to collapse in a controlled way under high vertical and off-vertical events, thus giving extra force-deflection to an occupant of the seat, and facilitating the deceleration of the force to the occupant of the seat to safe levels. The sacrificial hinge arrangement with its deformable slots enables a seat pan to drop, for example by 20 - 30mm. The amount of drop may be limited by stop means. The stop means may be one or more hook and catch arrangements. Other types of stop means may be employed. Where a hook and catch arrangement is employed as the stop means, then a seat belt anchorage spigot attached to a back portion of the seat may act as the catch. In this case, a hinge plate geometry on the seat pan may be such that a hook engages and limits the drop of the seat pan. It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, other types of sacrificial hinge arrangement may be employed. In all embodiments of the invention, the hinge arrangement may be attached to any suitable and appropriate part of the seat, and by any suitable and appropriate fixing point or fixing points. The seat 2 may be of any suitable and appropriate shape and design. The seat 2 may be an individual seat or a bench type seat. Where the seat 2 is an individual seat, then it may be a separate seat, or it may be connected to other seats. The seat 2 may alternatively be an aeroplane or helicopter, in which case the hinge arrangement 8 will operate if the aeroplane or helicopter crashed to the ground. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention.
