Problems solved by technology

[0009] However, this solution does not provide a means for indicating to the wearer of the pulsometer whether the wrist strap is sufficiently taut to ensure that the watch case is properly pressed against his wrist and thus the appropriate level of measurement accuracy
In fact, the patent states that the wearer of the disclosed pulsometer must tighten his wristband so that he does not experience an over-squeezing sensation similar to that experienced when wearing a traditional wristwatch

Embodiment Construction

[0024] Figures 1, 2a and 2b show a fastening strip according to a first general embodiment of the invention.

[0025] FIG. 1 shows a self-tightening fastening strip 1 . This strap 1 comprises a first main part 2 having two free ends 3 and 4 connected by strap fastening and length adjustment means.

[0026] The strap fastening and length adjustment means can be implemented in various ways known in the art. A preferred arrangement is shown here in a schematic manner in the form of a buckle 5 secured to the first end 3 of the strap 1 , for example by sewing. The second end 4 passes through the buckle 5 and folds back on itself, with means for holding the second end securely on the main part - ie the length of the strap 1 is fixed in this position. By way of example, as shown in FIG. 1 , on the end 4 of the strap and on the area adjacent to this end in the main part, there is distributed in a suitable manner a complementary hook and loop system, for example under the trade name ...

Abstract

The invention relates to a fastening band (19 in the form of a portable device (40) strap or wristband, for example provided with locking and length adjusting means (5). The inventive fastening band comprises an element (6, 42) displaying the tightening tension thereof in the form of a specific visual appearance identifiable by the user thereof in order to display to said user when the strip tightening tension is sufficient for a given use. The inventive fastening band is of particular interest when it is embodied in the form of a wristband for a wrist-carried pulse meter comprising optical measuring means. For this use, a tension force value sufficient for providing good accuracy of measurements is predefined and the display element characteristics are adapted to said value in such a way it makes it possible to display to the carrier that said value is attained when the wristband is adjusted on his / her wrist.

Description

technical field [0001] The invention relates to a fastening strap comprising at least a first and a second free end and means for fastening and adjusting the length of the strap. [0002] Typically, this type of strap can be, for example, a holding strip or a flat strap for securing a number of objects to each other. [0003] Preferably, the invention relates to such a strap embodied as a strap or wristband for securing a portable device, such as a watch, on the user's arm. Background technique [0004] Many wrist straps or straps for portable devices, especially watches, known from the prior art comply with the above definition. [0005] However, in the case of using a watch with multiple functions, such as when the watch has a pulsometer using a sensor located on the case back and must be in close contact with the wearer's wrist, it is necessary to ensure that the belt is proper tightness and must be maintained throughout the operation of the pulsometer. In fact, since ...
