Abstract

A chair intended for use in means of public transport is from considerations of safety provided with a stable profile frame (1), which is common to the seat and backrest of the chair. A safety belt is secured to said frame, the reel of which belt is attached to the mounting frame of said profile frame, whereas a passage for the belt is provided in the lateral area at the upper portion of said profile frame to provide for the desired three-point system for such belts. The belt end is fastened to profile frame (1) in the region between seat and backrest, whereas the belt latch (12) is fastened to the opposite side of the profile frame. This arrangement of the safety belt is also applicable to a chair the tilting angle of which is adjustable about a firm tilting point at the front edge of the chair.

Description

An arrangement in connection with a chair
The invention relates to an arrangement in connection with a chair, especially intended for vehicles, like busses, to provide for improved safety during transport.
It is generally known that public transport largely offers too poor safety for passengers, so that injuries to persons may easily occur in case of a car crash, a sudden stop, etc. The problem is especially relevant in connection with motor coaches and school busses transporting children. There is, however, a general request for enhanced safety for pas¬ sengers in busses and other vehicles used in collective transport.
A primary object of the invention is, thus, to provide an arrangement permitting the construction of a vehicle chair with improved safety with respect to its connection to the vehicle basis, with its hinging elements and the like, thus improving the safety for the person sitting in the chair. A second object of the invention is to provide an arrangement permitting three-point safety belts to be placed in a manner which is safe and ideal for their purpose, also in large vehicles having several seats side-by-side.
A further object is to permit three-point safety belts to be provided in vehicles in which the chairs are provided with devices for adjusting the angle of chair inclination. In aircraft seats safety belts have, in fact, been used for a long time, but they are two-point belts and would not provide sufficient safety, e.g. in a bus where very rapidly occurring impacts may cause severe injuries to persons in case of an accident.
These objects of the present invention is achieved by an arrangement the characterizing features of which are stated in the claims. A requirement for the arrangement according to the invention is that the chair is attached to a foundation or base member which is firmly connected to the support, e. g. by bolt connections, so that no undesired release may occur. By the invention a further difficult problem was solved, i.e. incorporation of a three-point safety belt at the same time as maintaining the possibility of adjusting backrest and seat in one and the same chair.
The invention is disclosed in more detail below with reference to an embodiment shown in the drawings, in which
Figure 1 shows a chair of a bus according to the invention, as seen in a diagrammatical perspective view, partly from the front, and
Figure 2 shows the chair of Figure 1, as seen from the rear and from below with the foundation and the rear seat plate removed.
In the drawing an embodiment of the invention is shown which embodiment is provided with a device for adjustment of the angle of inclination of the chair. Basically, the chair is built with a rigid profile frame forming the base of seat and backrest and being a rigid structural member. The seat cushioning proper with a cover, etc., may be designed in a conventional manner inside and about said frame, and is not described in detail. Profile frame 1 rests on a mounting frame 2 which in the shown embodiment is provided with holes 3 to be bolted to a foundation or base member which is mounted in the bottom of the vehicle in a collision-proof manner. Mounting frame 2 is, thus, efficiently secured. In case of an embodiment which is not an adjustable chair, mounting frame 2 will be firmly bolted up with profile frame 1. In the shown embodiment the front profile frame member 4 is, via a suitable tiltable connection, e.g. by the aid of journals 5, tiltably connected with mounting frame 2 at the front edge of the chair. At the rear portion of mounting frame and chair an adjusting mechanism is provided and will be disclosed in more detail below.
The adjusting mechanism proper comprises two spring members 13 which urge the seat up into its uppermost position, and a locking plate with fastening holes on each side, said plate being designated 14. By manipulating handle 16 a pin 15 on the mounting frame may be extracted from the main groove and the seat may then be pressed down into lower positions than the position shown in the Figure. Such an adjusting mechanism is very simple and rugged and will resist even high loads.
On the rear beam 6 of mounting frame 2 the roll or reel 7 of a three-point safety belt is secured. Belt 10 proper is pulled up on the rear of the backrest and is, preferably enclosed in a cover forming part of the backrest proper. Belt 10 extends up to a passage 9 in a fixture which is welded or bolted to profile frame 1 or forms an extension of the frame side, so that the belt passes out of the front of the backrest. From here it extends downwards to a fastening point at the transition region between backrest and seat. The fastening point at profile frame is designated by numeral 11. Numeral 11 also designates the fastening point to profile frame 1 for a safety belt latch 12, which is provided on the opposite side of the seat. In this embodi¬ ment the safety belt will be efficiently anchored to the sturdy profile frame and to the mounting frame of the chair, so that the belt is most securely anchored and may hold a person back in case of an accident.
By having reel 7 provided on the mounting frame and the remaining fastening points of the belt, i.e. points 11, on the profile frame, it is also possible to use this arrange¬ ment for an adjustable chair. Again, especially high safety is achieved by providing the tilting axis of the chair at its front .edge.
The shown embodiment may be modified in many different manners within the scope of the invention, since various kinds of mechanisms may be used for adjustment. The frame structure may also be adapted to various kinds of applicat¬ ions and the chair may, or may not, comprise arm rests as shown in the embodiment, depending on what is deemed more suitable. A neck-rest may be incorporated, as indicated in the drawing, or the frame structure proper may be extended to a higher level. The essential feature in this connection is that there is a sturdy profile frame portion to which passage 9 may be attached. The arrangement according to the invention is primarily intended for bus chairs, but it may obviously have many other applications, when chairs with safety belts of the three-point belt kind are desired. With a chair arrangement according to the invention inertia reel seat belts may also be used for aircraft seats, and will provide improved safety as compared to the simple two-point belts used at present. Many modifications both as regards design and application are, thus, possible within the scope of the invention.
