The collar is adjustably connected to the holder, and comprises at least two collar parts (30, 31) which are pivotally interconnected by means of a pivot pin (32) near the neck side or near the chest side and which can be interlocked near the chest side or near the neck side by means of a locking mechanism (39).

Description: A restraining device as well as a vehicle fitted with such a restraining device. The invention relates to a restraining device suitable for detachably restraining at least one person against a holder, which restraining device comprises a collar forming a closed ring, which in use is positioned at least partially near the neck side and at least partially near the chest side of the person to be restrained, wherein said collar is adjustably connected to said holder. The invention furthermore relates to a vehicle fitted with such a restraining device. The term vehicle is to be understood to include everything in which a person can be moved in seated, standing, reclined position etc., such as for example an aeroplane, a car or an amusement device. The holder may be a seat, a wall or other support, against which the person to be transported can be held in position. In a restraining device known from the applicant's international patent application WO 97/02878, a person is connected to the holder by means of a rigid, vertically adjustable bar. One problem connected with restraining a person to or in a holder is that relatively short persons, tall persons, relatively slender persons as well as corpulent persons can occupy the holder, all of whom must be securely held in position in the holder. The use of a vertically adjustable bar enables adjustment to the length of the person. Differences in girth between the various persons cannot be offset by means of the bar, however. In order to minimize the time required for boarding and leaving an amusement device in which the restraining device is used, it must moreover be possible to restrain a person in the holder relatively quickly. Furthermore the restraining device must not obstruct the person's view. Also in the case of planes, for example, it is important that persons can be safely restrained. The safety regulations for aeroplane passengers are clearly being tightened up. In addition, the safety requirements for the transport of troops have been made considerably stricter. Several investigations have been made, in particular with regard to safety, into laterally oriented seats which are often present in such applications. It has become apparent that when four-point or five-point seat belts are used, strong lateral movement and torsion of the upper body cannot be avoided in case of collision. In addition, there are uncertainties as regards the extent to which the cervical part of the vertebral column can be loaded in lateral flexion. The loads depend on the shear forces, the torques and the angle of the head with respect to the trunk. It is assumed that the risk of injury resulting from transverse forces and torques increases as the relative angle between the head and the trunk increases. Another drawback of the use of the four-point or five-point seat belts that have been used so far is the risk of the thin belt edges cutting into the skin. Furthermore there are inflatable systems which have been developed for military use, which, just like air bags, require electronic sensors and pyrotechnical gas generators. Such systems are not only expensive to buy, but they are also complicated and laborious, because they require constant monitoring and maintenance. Rescue hel icopters increasingly use laterally oriented seats or also revolving seats. Moreover, one requirement connected therewith is that rescue personnel must be able to attend to the patients to be conveyed during the flight. In order to do so, the attendant personnel must be able to leave their seats temporarily without having to remove their seat belts, and the seat belts must remain completely and securely in contact with the body. So far it has been attempted to achieve this by fitting all belt ends with belt tensioning mechanisms. It is attempted to prevent the shoulder belt from slipping off by connecting the two shoulder belts together behind the user by means of a further belt. The object of the invention is to provide a restraining device by means of which persons differing in size can be restrained against a holder relatively quickly and securely. This objective is accomplished with the restraining device according to the invention in that the collar comprises at least two collar parts, which are hinged together about a pivot near the neck side or near the chest side and which can be interlocked near the chest side or near the neck side. When taking his place in the holder, the person will arrange the collar part round his neck and shoulders, after which he will lock them. The collar forms a support for the chest and the neck of said person. Then the collar is adjusted in directions parallel to and transversely to the holder and locked in position with respect to the holder, in such a manner that the occupant is securely restrained in the holder by means of the collar. The collar may be formed ergonomically, so that it will comfortably abut against the wearer. It is also possible to lock the collar in position with respect to the holder only in case of emergency and to allow movement of the collar with respect to the holder during transport, for example in a helicopter. Since the collar parts are capable of hinging movement with respect to each other and of being interlocked, the collar can be easily fitted round the user's neck and shoulders, wherein the collar parts only need to be interconnected on one side. It is noted that US-A-4,063, 778 discloses a collar which is to be positioned over the person's head and which must subsequently be connected to a holder on two sides. The positioning of the collar over the person's head is a relatively time-consuming activity. Moreover, the collar needs to be so designed that a person's head can pass through it. Such a requirement is not made of the collar according to the invention, which makes it possible to design the collar according to the invention optimally for adequate support of the neck, the shoulders and the upper body. In addition, with the collar according to the invention the collar parts only need to be interconnected on one side, so that the fitting of the collar can take place relatively quickly. It is furthermore noted that US-A-3, 524, 679 discloses a device for securing a person in a holder, which device comprises a jacket to be put on by the user. Then the jacket must be connected to a holder in four places. The putting on of the jacket, with the user having to put his arms through armholes, is relatively time-consuming, as is the connecting of the jacket to the holder in several places. The restraining device according to the invention has the following advantages, among others. It is simple to operate, that is, the collar can be put on and taken off quickly and in a foolproof manner, also when the user is wearing gloves. When the user is supported against the holder in seated, standing or reel ined position, the collar will firmly abut against the user's body. When the user gets up or is attending to patients or performing other activities, the collar will remain securely positioned against his body. In case of lateral decelerations, the person's upper body can be adequately retained in the starting position in lateral direction by means of the collar. The collar will reduce the extent of rotation of the upper body in case of collisions. The collar effects a secure support of the user's neck, shoulder and upper body, with the ears being spared. With the prior art devices, which comprise a relatively hard bar, the person hits the bar with his ears, which is undesirable, of course. The collar will reduce the relative angle between the head and the neck in case of deceleration in lateral direction. The collar is much cheaper to buy than inflatable systems, and apart from the usual optical checks and maintenance it does not require any care. The collar does not have a higher system weight than pyrotechnical systems. One embodiment of the restraining device according to the invention is characterized in that the collar is connected to the holder by means of at least one belt which is capable of being tensioned. A belt which is capable of being tensioned enables free movement of the collar moved with respect to the holder upon being fitted, whereby persons differing in size can fit the collar round their necks without any difficulty. Then the belt is tensioned and the collar and the person wearing the collar are pulled firmly against the holder. If three belts are provided, the collar can be tensioned in three directions, thus fixing the collar with respect to the holder. The three belts may be separate belts, or they may form part of one elongated belt. By using a number of separate belts, however, an additionally secured restraining device is obtained, which will also fix the person in position if one of the belts should fail. The belt may comprise any belt-li e or granular material , such as belts, cables, ropes, etc. In order to reduce the extent of lateral movement, the points of attachment of the belts to the holder may be provided in a lateral position. In order to reduce the extent of rotation of the upper body, the collar according to the invention can be attached in several points. The surface of a collar according to the invention is furthermore easy to clean and to disinfect, unlike belts, the fabric of which easily absorbs blood and other fluids and impurities. This advantage is especially of importance in case of use in rescue ships and aeroplanes. In those cases wherein the user of the collar needs to leave the holder (for example a seat) temporarily, the direction in which the belts extend will change. It is important thereby that the attachments are so constructed that they will ensure an optimum transmission of forces at all times. When tiltable belt tensioning devices are used, said belt tensioning devices will adapt themselves to the respective direction of pulling. Preferably, the belts are connected to plates incorporated in the collar, so that a strong and secure restraining device is obtained. The invention will now be explained in more detail with reference to the drawings, in which: Figure 1 is a perspective view of a restraining device according to the invention; Figure 2 is a side view of the restraining device of Figure 1; Figure 3 is a perspective view of the restraining device of Figure 1, showing a relatively small person present therein; Figure 4 is a view of the restraining device of Figure 1, showing a relatively tall person present therein; Figure 5 is an exploded view of a first embodiment of a collar of a restraining device according to the invention; Figure 6 is a front view of the collar of Figure 5; Figures 7A and 7B show the collar illustrated in Figures 5 and 6 in, respectively, open position and locked position; Figure 8 is a side view of a head rest attached to a collar according to the invention; Figures 9A and 9B show a second embodiment of a collar according to the invention in, respectively, open position and locked position; Figure 10 shows another embodiment of a restraining device according to the invention; Figures 11A-11D are perspective views of a restraining device according to the invention which is provided with an evacuation device; Figures 12A and 12B are perspective views of another evacuation device according to the invention; Figure 13 is a front view of another embodiment of a restraining device according to the invention; Figure 14 is a side view of the restraining device of Figure 13; and Figures 15 - 18 are front view of yet further embodiments of restraining devices according to the invention. Parts corresponding to each other are indicated by the same reference numerals in the figures. Figures 1 and 2 are a perspective view and a side view, respectively, of a restraining device 1 according to the invention, which comprises a seat-like holder 2, against which a person 3 is detachably restrained by means of a collar 4 and belts 5 - 8 secured to collar 4. Collar 4, which will be explained in more detail with reference to Figure 5, forms a closed ring or loop round the person's neck, wherein collar 4 is provided on the neck side with a head rest 9, which supports the head 10 of person 3. Collar 4 furthermore comprises a part 11 abutting against the chest side of person 3, and parts 12 interconnecting head rest 9 and part 11, which abut said person's shoulders. Belts 5, 6 are attached to shoulder parts 12 on either side of head rest 9 by means of attaching members 13, 14. Belts 7, 8 are attached to a side of the chest part 11 remote from the shoulder parts 12 in a similar manner by means of attaching members 15, 16. The belts 5, 6 extend through the back 17 of seat 2, and they are attached to belt tensioning mechanisms 18 on a side of back 17 remote from collar 4. Belts 7, 8 extend through a seat part 19 of seat 2, and they are attached to belt tensioning mechanisms 18 on a side of seat part 19 remote from collar 4. Collar 4 is furthermore provided with handles 20, which can be gripped by a person upon fitting the collar 4. When the restraining device 1 is used in an amusement device, the person can also grip the handles 20 during the time he stays in the amusement device. The restraining device 1 as shown in Figures 1 and 2 furthermore comprises a hip bar 21, by means of which the upper legs 22 of person 3 are pressed against seat 2. Such a bar 21 is known per se and consequently it will not be described in detail herein. The restraining device 1 according to the invention can also be used without a hip bar 21. Before entering into a more detailed discussion of the construction of collar 4, the operation of the restraining device 1 according to the invention will be explained with reference to Figures 3 and 4. In the situation as shown in Figure 3, a relatively small person occupies the seat 2, and collar 4 has been fitted round his neck and in abutment with his chest. Subsequently, belts 5 - 8 have been tensioned by means of belt tensioning mechanisms 18, with person 23 being pulled firmly against seat part 19 and back 17 by means of collar 4. Collar 4 is thereby moved in directions opposite the directions indicated by arrows PI, P2. In the situation which is shown in Figure 4, a relatively tall and corpulent person 24 occupies seat 2. Compared to the situation shown in Figure 3, collar 4 has been moved both in the direction indicated by arrow PI and in the direction indicated by arrow P2. After collar 4 has been fitted round the neck and against the chest of person 24, collar 4 is again pulled against seat part 19 and back 17 by means of the belt tensioning mechanisms 18 of belts 5-8. Both in the situation shown in Figure 3 and in the situation shown in Figure 4 the belt tensioning mechanisms 18 are locked after tensioning belts 5- 8, so that person 23, 24 is undetachably connected to seat 2 temporarily. Since collar 4 is adjustable in practically all directions with respect to seat 2 upon being fitted, collar 4 can readily be used by persons of varying size, whilst said persons can subsequently be fulled firmly against seat 2 by means of collar 4. Figure 5 is a perspective exploded view of collar 4 of restraining device 1. Collar 4 comprises two collar parts 30, 31 made of a relatively rigid material, such as a plastic, which are hinged together near the neck side by means of a hinge 32. Each collar part 30, 31 comprises a neck portion 33, a shoulder portion 34 connected thereto and a chest portion 35. Each shoulder portion 30, 31 furthermore includes a plate 36 of a metal or other force-transmitting material, which is connected to the plastic collar part 30, 31 on a side which in use is remote from the user. Metal plate 36 extends between shoulder portion 34 and the lower end of chest portion 35 remote from shoulder portion 34. The metal plates 36 are provided at their ends with the means of attachment 13 - 16, to which the belts 5 - 8 are attached. Furthermore attached to metal plates 36 are handles 20. Also mating parts 37, 38 of a locking mechanism 39 are connected to metal plates 36. Each collar part 30, 31 is provided with a soft cushion 40, 41 of plastic material on a side that faces towards the person in use. Due to the presence of cushions 40, 41, collar 4 comfortably abuts against the neck, the shoulders and the chest of the person. Metal plates 36 and the belts 5 - 8 provide an adequate transmission of the forces exerted on belts 5 - 8. Figure 6 shows a front view of collar 4, wherein parts 37, 38 of the locking mechanism are interconnected and collar parts 30, 31 form a closed, ring-shaped collar. Arrows P5 - P8 indicate the directions of the forces that are exerted on belts 5 - 8 upon tensioning of the belts 5 - 8. Figures 7A and 7B show the collar of Figure 5 in open and locked position, respectively. Hinge 32, by means of which collar parts 30, 31 are interconnected, is preferably provided with a torsion spring (not shown), by means of which collar parts 30, 31 are urged to the open position as shown in Figure 7A. As a result, a person taking up position in seat 2 only needs to close collar parts 30, 31, so that it can easily be verified whether or not a person has put on collar 4. In the position which is shown in Figure 7B, the collar parts 30, 31 have been moved together against the spring force of the torsion spring present in hinge 32 and been interlocked by means of interlocking parts 37, 38 of locking mechanism 39. Figure 8 shows a side view of head rest 9 of collar 4, by means of which the head 10 of a person 3 is firmly supported. Figures 9A and 9B show an alternative embodiment of a collar 40 according to the invention, wherein collar parts 40, 41 are hinged together near the chest side and are capable of being interlocked near the neck side. Figure 10 shows another embodiment of a restraining device 43 according to the invention, wherein collar 4 is only connected to holder 2 by means of a single belt 44 near the neck side, whilst collar 4 is connected to holder 2 by means of two belts 45, 46 near the chest side. A strong fixation of collar 4 and of the person present therein with respect to holder 2 is also possible by means of three belts. Figures 11A - 1ID show an evacuation device 50 according to the invention in several stages of being fitted. The evacuation device 50 makes it possible to remove a person 3 from seat 2 in cases wherein seat 2 has come to a standstill in an undesirable place in for example a roller coaster-type amusement device. Evacuation device 50 may be stored under the seat part 19 of seat 2, for example. The evacuation device 50 as shown in Figures 11A - 1 ID comprises a belt 51, whose ends 52, 53 are gripped by person 3 himself or by a third party and moved in directions indicated by arrows P9, P10. Then a ring 54 connected to belt 51 is gripped and moved in the direction indicated by arrow Pll (see Figure 11B). The belt ends 52, 53 are passed over the upper legs 22 of the person and through the ring 54 in the directions indicated by arrows P12, P13 (see Figure 11C) and subsequently through the means of attachment 15, 16 of collar 4 in the directions indicated by arrows P14, P15. Following that, the ends 52, 53 of belt 51 are passed crossways behind the back of person 3, in the directions indicated by arrows P16, P17, and connected to the means of attachment 13, 14 of collar 4. Then the belts 5 - 8 are detached from collar 4 (see Figure 11D), whilst the person can be removed from seat 2 by means of the evacuation device 50 connected to collar 4. The presence of such an evacuation device 50 is in particular important if person 3 is so positioned with respect to holder 2 in the amusement device that the simple removal of belts 5-8 would cause the person to fall from seat 2, as would for example be the case when the person is suspended in the seat. Figures 12A and 12B show an alternative evacuation device 60 according to the invention, respectively before and after being connected to collar 4. The evacuation device 60 is provided with an H-shaped belt 61, which comprises four belt legs 62 - 65 and a bridge portion 66 connecting belts legs 62 - 63 to belt legs 64 - 65. Each belt leg 62 - 65 is provided at one end thereof with an element 67, which is to be secured to means of attachment 67. Belt legs 64, 65 are furthermore provided with a loop 68, through which element 67 can be passed. Belt parts 64, 65 are passed over the upper legs 22 of the person 3 to be evacuated in the directions indicated by arrows P18, P19 so as to attach the evacuation device 60 to a person. Then the elements 67 of belt legs 64, 65 are passed through loops 68 and subsequently moved in the directions indicated by arrows P20, P21 and connected to the attaching members 15, 16 of collar 4. Belt legs 62, 63 are passed behind the person's back and over the person's shoulders. Then the elements 67 or belt legs 62, 63 are connected to the attaching members 13, 14 of collar 4 (see Figure 12B). Figure 13 shows another embodiment of a restraining device 70 according to the invention. The restraining device 70 comprises two collar parts 30, 31, which can be connected to a locking mechanism 73 via their ends 71, 72. Locking mechanism 73 is connected to two hip belt portions 7, 8 and additionally to a cross belt 74, if desired. The collar parts comprise cushion portions, which are adapted to the shape of the neck and the body of an average user and which comprise radii opposite the neck, and which are interconnected by means of at least one hinge 32. The ends 71, 72 of the collar are inserted into the locking mechanism 73 so as to be locked in position. As a result, the cushion portions are pulled against the user's body. When the locking mechanism 73 is being opened, the two collar parts 30, 31 are pulled apart by springs (not shown) disposed in or above hinge 32, as a result of which a wider exit opening is provided between the ends 71, 72. Figure 14 is a side view of the restraining device 70 of Figure 13, wherein pivot 75 of hinge 32 is clearly shown. Pivot 75 slopes upwards towards the body vertical 76. When the collar parts 30, 31 are being moved apart, the collar parts are pivoted slightly upwards, as a result of which a relatively large entry and exit opening is obtained. As is shown in Figure 15, structural elements 77 are present on the upper side of collar parts 30, 31, which elements consist of belts or of suitable belt-like, force-transmitting materials, as a result of which the collar parts 30, 31 need not have a force-transmitting function. The lower ends of the structural elements can be detachably connected, directly or indirectly, to the locking mechanism. Belts can be connected to the structural elements 77 for direct or indirect attachment to the holder in a vehicle, an aeroplane or an amusement device. Figure 16 shows an embodiment of a restraining device 78 according to the invention, wherein the collar parts 30, 31 are attached to a wall 79 of for example an aeroplane by means of belts. Attached to the collar part 30, at the level of a user's shoulder, is a belt 80', which is connected to wall 79 with an end remote from collar 30. Attached to collar part 31, at the level of the shoulder part, is a belt 80", which is connected at an end remote from collar part 31 to a belt tensioning mechanism 81. Belt tensioning mechanism 81 is capable of tilting movement in directions indicated by double arrows Rl, R2. This enables the belt tensioning mechanism 81 to adjust itself to the direction of the pulling force exerted on belt 80''. Belts 80', 80" extend substantially horizontally and in line with each other, thus reducing the extent of lateral movement of the person in case of collision. Since belts 80', 80" are subjected to very high loads in case of collision in forward direction, device 78 furthermore comprises a belt 80'", which is connected to the centre of collar parts 30, 31 with one end and to a belt tensioning mechanism 82 with another end. Belt tensioning mechanism 82 is capable of tilting movement in the directions indicated by double arrow P3. Said belt 80"' ensures a direct and thus reduced transmission of forces between the holder and wall 79 whilst at the same time allowing a relatively small movement of the person. Figure 17 shows an arrangement of V-shaped belts 83, 84, a first V-arm 83 of which is connected substantially behind the user, whilst the second V-arm 84 is connected to the collar part 31 at a point slightly below the user's collarbone so as to minimize the extent of rotation of the user's upper body. The second V-arm 84 may be elastic in longitudinal direction along its entire length or it may comprise an elastic part, which elastic arm or arm part can replace the function of the springs in hinge 32, if desired. It is also possible to adjust the relatively small change in length of said V-arm 84 in dependence on the user's body size. Preferably, the elongation which the elasticity enables can be adjusted so that the V-arm 84 is fully extended in the longest position that is possible, and that it is capable in this position of absorbing the force that is being exerted. In Figure 17, collar part 30 comprises a triangular, elastic fabric 85 rather than V-shaped belts 83, 84, wherein the triangular fabric is connected to collar part 30 with one longitudinal side and, directly or indirectly, to the holder in a connecting point 86 located opposite said longitudinal side. Flat fabrics or materials 85 have the advantage of being light-weight whilst at the same time being capable of absorbing relatively large forces. The flat form of the fabric 85 will also restrain the shoulder joint region in case of collision. Preferably, the fabric is linearly connected to the collar 30, whereby the elasticity is utilized in such a manner that it is fully extended in the abutting position so as not to allow any further play in case of collision. Figure 18 shows a restraining device with adjustable connecting parts 87 mounted therein, which parts are connected to the ends 70, 71. The connecting parts 87 are each accommodated in a liner in such manner as to be capable of absorbing lateral forces. In addition, they are loaded by a spring in such manner as to adapt to the body size and the seated or standing position of the user. In case of collision, said connecting parts will be locked against further movement by locking mechanisms (not shown), thus retaining the user in the position he occupies.
