(54) VERTICALLY ADJUSTABLE SEAT BELT ANCHORAGE
(71) We, DAIMLER-BENZ AKTIENGE
SELLSCHAFT, of Stuttgart-Unterturkheim,
Germany, a Company organised under the laws of the Federal Republic of Germany, do hereby declare the invention for which we pray that a patent may be granted to us and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to a vertically adjustable seat belt anchorage, accommodated in a hollow member of a vehicle, for adjusting the height of an upper anchorage or return fitting for the shoulder belt of a safety belt system.
The purpose of arrangements of this kind is to ensure that the upper anchorage or return fitting for a safety belt is positioned not only in accordance with the average values suitable for the majority of users, but also to adapt the upper anchorage point of the safety belt to extreme body sizes.
Such anchorages, which are capable of continuously variable adjustment in height in dependence on the position of the seat in the vehicle and which permit adaptation of the upper anchorage point of the safety belts to extreme body sizes, are normally held, but not fixed, in their respective positions solely by a tranmission device, for example a flexible cable, connecting the seat to the device, so that under abnormal running conditions, for example during heavy braking or in the event of a collision, the device and consequently the anchorage or return fitting will be undesirably displaced, which would entail greater risk of injury to the wearer of the seat belt.
The problem underlying the invention is that of providing an anchorage which in a simple and inexpensive manner contributes towards eliminating the disadvantages and discomfort caused by fixed belt anchorage points when the users of the belts are exceptionally tall or short, and which in addition is able to hold the return fitting in a fixed position, not only in normal travel but also in the event of heavy braking or in the event of a collision.
According to the invention, there is provided a vertically adjustable upper return anchorage for the shoulder belt of a vehicle safety belt system which is disposed in a hollow member of the vehicle, the anchorage including a steplessly adjustable slide member displaceably guided in the hollow member, one wall of which is provided with at least one row of teeth or recesses and in which at least one corresponding series of teeth on a locking member engages when tensile forces applied to the belt exceed the forces applied to the belt by a user during normal travel, against the action of at least one spring which in normal travel urges the locking member towards a position of disengagement of the teeth, wherein t;2le or each row of teeth or recesses provided on the hollow member is provided on the inside of the wall of the hollow member directed towards the interior of the vehicle.
According to one feature of the invention a vertically displaceable slide block is located in the slide member which cooperates with the locking member and which when corresponding tensile forces are applied to the belt moves the locking member substantially transversely to its own direction of movement until the teeth on the locking member engage the teeth on the hollow member.
In a preferred embodiment of the invention, the slide block is slidably disposed on the locking member by means of mutually inclined sliding surfaces in such a manner that the sliding surfaces lying against each other form an angle of the order of 45 to the direction of movement of the slide block.
According to another feature of the invention, a return spring is provided which is supported against the wall of the hollow member and which presses the locking member in the direction of disengagement into a space or recess in the slide.
In another feature of the invention, the sliding element is connected to a fastening means securing the upper end of the belt to the anchorage, the fastening means having a stem guided for vertical displacement on the one hand in a slot provided in the opposite wall of the hollow member to that on which the locking teeth or recesses are provided, and on the other hand in a slot provided in the slide.
Although means are known by which the height of the anchorage points of a safety belt can also be adjusted they permit only step wise adjustment of the anchorage points, the safety belt anchorage being brought into the locking position after each height adjustment.
The invention further provides for a transmission device, for example provided with a flexible cable, to connect the slide to a seat in the vehicle in which during the longitudinal adjustment of the seat effects the continuously variable displacement of the slide against the action of a spring.
An embodiment of the invention will now be described more fully by way of an example and with reference to the accompanying drawings, in which:
Figure 1 shows diagrammatically the overall arrangement of the anchorage as installed in a motor vehicle,
Figure 2 shows the anchorage, which is displaceable in a hollow member of a vehicle, for example a door pillar, for the vertical adjustment of an upper safety belt anchorage or return fitting, and
Figure 3 is a section taken along the line 11-11 in Figure 2.
In the hollow member 1 which is for example the central pillar of a passenger motor vehicle, not further illustrated, an assembly 5 is accommodated which as shown in Figures 2 and 3 consists of a slide 2, a slide element or block 3, and a locking member or block 4, the assembly serving to adjust the height of an upper return fitting or anchorage 6 for the shoulder belt of a safety belt system.
The slide 2 is in the form of a right parallelepiped and has a recess 7 in which a locking member or block 10, fitting the recess 7, is guided for transverse displacement with respect to the direction of the movement of the slide 2 against the force of one or more return springs one of which is partially illustrated in Figures 1 and 3.
The slide 2 is connected to the seat 27 by means of a transmission device 26 as shown in
Figure 1. The transmission device 26 shown in the drawings consists essentially of a "Bowden..
(Registered Trade Mark) cable in which in the event of a displacement of the seat 27 from the normal position I to the position of II moves the slide 2 downwards in the hollow member 4 from the position A to the position B, or allows it to rise into the position C as soon as the seat is moved into position III. The vertical displacement of the assembly 5 is thus continuously variable and the upper belt anchorage can be automatically adjusted to any body size of
the user of the belt.
When the seat is returned to its normal position I, the slide 2 is pulled to its corresponding upper poistion by means of a tension spring. If the distance travelled by the slide should be shorter than the adjustment path of the seat, a compensating device can be interposed in the cable in the region of the seat.
The slide 2 is guided for continuously variable or stepless displacement in the hollow member 1 and is provided with the large recess 7 in which the slide block 3 is vertically displaceable, the locking member 4 being guided for displacement transversely to the direction of movement of the slide block 3 against the pressure of a return spring 8.
The slide block 3 has an inclined sliding surface which leans against a similarly inclined sliding surface 10 of the locking member 4, the mutually opposed sliding surfaces 9 and 10 being at an angle of substantially 45" to the direction of movement of the slide block 3 or the slide 2.
As shown in Figure 2, the locking member 4 is provided with two rows of teeth 11 which lie parallel and side by side and which are associated with the similar rows of teeth 12 provided on the inside of the outer wall 13 of the hollow member, as shown in Figure 3.
In the hollow member wall 14 disposed opposite the wall 13 a slot 15 is provided which faces a similarly directed slot 2a in the slide 2.
A threaded bolt 16 screwed to the slide block 3 passes through the two slots 15 and 2a, this bolt sliding up and down with the aid of a sleeve 18 surrounding the bolt stem 17 in the slot 15 during vertical displacement of the device, and also sliding downwards in the slot 2a when the belt is subjected to a higher than normal loading. The upper end fitting 6 of the safety belt is pivotably mounted between the sleeve 18 and the bolt head 19 of the bolt 16.
For the vertical adjustment of the upper anchorage or return fitting, the slide 2 is connected by means of a transmission device 20 which consists essentially of a "Bowden" cable, to one of the adjustable front seats of the vehicle. If the seat is moved forwards from a pre-determined normal position, the slide 2 will be displaced downwards in the hollow member 1 whereas conversely if the seat is moved backwards for a taller occupant, the slide 2 and consequently the return fitting and upper anchorage 6 will be moved upwardly.
If the belt is now subjected to a higher than normal load by a wearer, for example, as a result of excessive braking, or in a collision, the slide block 3 is pulled downwardly and in turn pushes against the locking member 4 which causes the latter to be pressed laterally against the force of the return spring 8 until its teeth 11 engage the teeth 12 on the wall 13 of the hollow member 1.
As soon as the belt is relieved of excessive loading, the return spring 8 presses the locking part 4 and the sliding element 3 back towards the disengaged position, so that the teeth 11 and 12 are out of contact and the previously locked slide is now free again to move longitudinally in the hollow member 1 in conformity with adjustment of the seat.
The vertical displacement of the upper belt anchorage may optionally be effected by hand.
For such a purpose the transmission device is replaced by a friction element, for example a spring pressure plate preventing the assembly 5 from slipping along the hollow member 1. Such a friction element could be disposed between the slide and the interior of the hollow member.
