Abstract

Previous belt systems in safety clothing are designed in such a way that they are integrated into the clothing and enclose the body at chest height. At both ends of the belt there are locking elements which, when brought together, close the rescue belt. At one end of the belt there is also a securing system consisting of a locking element and a securing pulling device with which the wearer of the clothing can hook onto a solid object to prevent falls. Since this safety system is only attached to one end of the belt, the entire belt can be pulled out of the jacket under load if the front fastener of the belt is not (properly) closed. The new belt system overcomes this problem without disturbing when not in use. The decisive factor for this inventive solution is that the securing pulling means (2) is arranged firmly and permanently at one end of the chest belt (1). At the other end, the lanyard (4) is attached to a single or multiple lock carabiner (5) and the holding and rescue eyelet (7). Fall protection is carried out by hooking the safety pulling device (2) into the rescue eye (7) on the lanyard (4) of the belt, next to the front fastener (6), so that the belt cannot be pulled out of the jacket and the person is secured against a fall Lifebelt for safety clothing

Description

introduction

The invention relates to a rescue belt such as is typically used for fire-fighting jackets and for other items of safety clothing.

Rescue belts of this type as an integral part of a fire service jacket are able to carry the body weight of at least one person. They are used for holding, securing, retaining and positioning. They can also be used for self-rescue in an emergency.

State of the art

Rescue harnesses of the aforementioned type are known from the prior art. They basically consist of a chest strap enclosing the upper body of the person wearing it, which is provided with closure elements at its two opposite ends, the two closure elements being able to be coupled to one another in a force-transmitting manner.

The chest strap is typically located in a tunnel of the fire service jacket that runs around the chest area.

The longitudinal axis of the tunnel system of the jacket for receiving the chest strap runs approximately perpendicular to the jacket fastener, typically a zipper, with access to the strap ends with the two coupling elements of the chest strap via an opening in the front of the jacket.

It is also state of the art that holding and rescue eyelets and safety pulling means are arranged in a force-transmitting manner in the vicinity of one of the two locking elements of the chest strap.

Named holding and rescue eyes as well as connected safety pulling devices are used, for example, to hook onto a ladder and thus secure yourself from falling.

Since great forces act on the securing traction device and it must not tear, a belt or a rope or a chain is provided as the securing traction device.

For power transmission in the event of a fall, the safety traction device is firmly connected to the chest strap, so that an unintentional separation of the two is impossible. The fixed connection between the securing means and the chest strap can also be made detachable by means of a single or multiple lock carabiner.

The aforementioned prior art is comprehensive, for example, in the laid-open specification DE 10 2014 018 929 A1 described, which relates to an inventive solution with an openable holding and rescue eyelet for replacing the securing means.

Furthermore, the state of the art is that a connection to the holding and rescue eyelets of the chest strap is established by means of a locking element, typically by means of a snap hook at one end of the safety pulling device, so that the person wearing the fire fighting jacket with integrated rescue system can be attached to a fixed object, for example Example of a ladder that can hook in to prevent falls.

If the person slipped and the contact with the ladder was lost, the safety device that was hooked onto the ladder would be tightened and the chest strap activated via the snap hook at the end of the safety pulling device, which prevents the wearer of the jacket from falling via the fire service jacket, provided the locking system for the chest strap was properly closed beforehand or is not accidentally uncoupled again afterwards due to a mistake or malfunction.

According to the current state of the art, a chest strap that is not closed for whatever reason would in the case described lead to the chest strap being pulled out of the tunnel of the fire service jacket and thus to the wearer of the jacket falling.

If the safety device of the fire brigade jacket, consisting of a chest strap fastener, snap hook, safety pulling device, lanyard and retaining and rescue eyelet, is temporarily not used, the named system components should not be a hindrance for the wearer during normal use of the jacket and should not disturb him.

For this purpose, too, the prior art offers receiving pockets according to the invention only on an outer front side of protective jackets, such as the patent specification DE 10 2011 084 685 B4 can be taken.

task

The present invention is initially based on the object of providing a rescue belt that prevents the chest belt from being pulled out of the firefighter's jacket even when the chest belt's closure system is not or not properly closed, which is intended to eliminate the risk of falling and is a serious safety shortcoming of all previously known systems.

Furthermore, the object of the invention is to simultaneously develop a fire service jacket with an integrated rescue system, the safety devices and system components of which are required for this purpose can be used quickly and easily, but should not interfere or hinder the normal wearing of the jacket outside of use.

solution

The rescue system according to the invention consists of a chest strap, on one side end of which one end of a safety pulling means is firmly and permanently attached in the vicinity of the locking element.

A first single or multiple lock carabiner for securing, holding and restraining is attached to the other end of the safety pulling device.

At the other end of the chest strap, a fixed or fold-out holding and rescue eyelet is built into the locking element.

One end of the lanyard is firmly and non-detachably attached to the fixed or unfolded holding and rescue eye or in its vicinity.

At the other end of the lanyard, a second single or multiple lock carabiner or a D-ring is attached, which is traditionally used in dangerous situations to hook in a safety rope for abseiling.

Just as on the securing traction means, great forces can also act on the connecting means, so that a belt or a rope or a chain is also provided for this.
The preferred use of a belt or a rope is due to their relatively low weight, while the use of a belt also has the option of uncomplicated sewing for a force-transmitting, fixed connection with the chest belt or, by means of a sewn loop, with an attached holding and rescue eyelet.

It is crucial for the present inventive solution that the securing traction means is arranged with a first single or multiple lock carabiner at one end of the chest strap, while the connection means with a second single or multiple lock carabiner and the holding and rescue eyelet is arranged on the other Are arranged at the end of the chest strap.

The arrangement of the aforementioned system components at the two ends of the chest strap can also be done "reversed".

For self-rescue in an emergency, according to the invention, the single or multiple lock carabiner at the end of the safety pulling device is either attached to the fixed or fold-out holding and rescue eyelet on the other side of the chest strap or on the second multiple lock snap hook at the end of the lanyard, which is also located on the other side end of the chest strap is detachable and firmly hooked.

The fact that the separate locking system of the chest strap is firmly coupled at the same time or that it accidentally does not release again is no longer essential with regard to effective fall protection.

Pulling out the chest strap is prevented solely by the described connection of the two snap hooks on the two different side ends of the chest strap or, alternatively, by hooking the snap hook on the safety pulling means on one side into the fixed or unfolded holding and rescue eyelet on the other.

Since the safety pulling device with attached single or multiple lock carabiner is traditionally used for fall protection, for example by hooking it onto (or around) a fixed ladder, it is particularly advantageous for its handling if it has a total length between approx. 70 cm and 90 cm cm, so also for the present inventive solution.

The connecting means between the holding and rescue eyelet and the second snap hook, which is arranged according to the invention at the other end of the chest strap, has a length between approx.
The length of the connecting means, which is shorter in relation to the securing traction means, is intended to exclude the malfunction of the accidental hooking of the second snap hook on the holding and rescue eye.

The arrangement according to the invention of several system components, specifically of securing pulling means and first snap hook on the one hand and holding and rescue eyelet, connecting means and second snap hook on the other hand, at two different ends of the chest strap (and thus on two different jacket halves in the area of the front part), requires in comparison to The state of the art described also new solutions for accommodating the essential components of the rescue system in the fire fighting jacket during the time when they are not needed and used due to the application.

For this purpose, two so-called Napoleon pockets are installed in the front area of the jacket, on the left and right inside to the jacket closure.
In their typically rounded shape, they have effective outer side lengths of approx. 10 cm and 24 cm, which allow easy stowing of the named security components and are adapted to their dimensions.
The inside Napoleon pockets, which are used to hold the safety system when not in use, are accessible from the outside even when the fire service jacket is closed.

The named access area is arranged in terms of height where the locking system for the built-in chest strap of the fire service jacket is also located.
The access, which is used for access to the two Napoleon pockets from the outside and for closing the chest strap, is protected by two cover flaps that are attached to the outside of the chest area when the jacket is worn normally.

The two cover flaps, which can be opened to the left and right, preferably by means of a detachable Velcro fastener, enable quick access to the system components of the rescue belt stowed in the two Napoleon inner pockets, even when the jacket is closed, including the fastening system for the chest belt that can be operated in the event of an emergency, typically a click or other safety lock ( 6th ) or a single or multiple lock carabiner.
