A PERSONAL SAFETY GARMENT
The present invention relates to a personal safety garment of the kind that is worn by a work person on a scaffolding or other elevated structure.
It is known to provide a work person with a safety harness and lanyard in elevated environments. The safety harness generally comprises a plurality of strap loops that are worn over the shoulders and upper thighs of the user and often includes a waist or chest strap that interconnects the two shoulder loops. The harness is connected to the lanyard for attachment to an anchorage point on the elevated structure on which the user is working. The lanyard generally incorporates a fall-arrest device so that in the event of a fall the work person is brought to rest without injury. The harness is designed to distribute the fall-arrest forces around the user's body.
Existing safety harnesses of the kind described above are generally difficult to don quickly as the wearer has to insert his/her limbs through the appropriate loops defined by the strapping and then make adjustments to the tension of the straps so that the harness is both comfortable to wear and will perform effectively. Moreover, there is a tendency for the straps of the harness to snag with or abrade against parts of the elevated structure or other equipment being used by the wearer. In consequence of these problems, some workers are reluctant to wear the harness at all times.
Recent legislation has imposed increased emphasis on the requirement that employers ensure workers are equipped with their own personal safety equipment and that it is used effectively.
It is known to incorporate a safety harness into an overall or other garment. One such example is described in European patent application No. 96303730.4 (publication No. 0744192) in which there is disclosed a fall-protection safety suit in which there is mounted a safety harness. The strap assembly is configured for automatic adjustment so that in the event of the fall the harness becomes tight-fitting around the wearer of the suit. In order for automatic adjustment to be effective sections of the harness straps are received in sleeves sewn to the inside of the suit. The sleeves are dimensioned so as to permit the straps to move through the sleeves during automatic adjustment to the tight-fitting position. A disadvantage of this particular
suit is that, in use, there may be, over time, abrasion of the straps sections within the sleeves particularly in the event of a fall. Since the relevant strap sections are hidden within the sleeves inspection for such wear is difficult and therefore there is a danger that the wearer may be wearing an unsafe harness.
It is an object of the present invention to obviate or mitigate the aforesaid disadvantage.
According to the present invention there is provided a personal safety garment having leg, arm and torso sections and comprising a safety harness integral therewith and disposed on an interior surface of the garment such that when the garment is turned inside-out the harness can be readily inspected.
Since the harness is integral with the garment there is no frictional relative movement therebetween and therefore no abrasive wear to the harness. By tailoring the garment (and therefore harness) size to the size of the intended wearer there is no requirement for an adjustable harness. A further cause for abrasive wear is thus eliminated along with the risk of snagging of adjustment buckles or other devices.
The integrity of the garment can be ascertained simply by turning the suit inside-out for inspection. Thus the present invention not only provides for significantly improved personal safety but also reduces the effort and time involved in safety inspections.
Since the harness is integral with the garment and disposed on the inside there is no risk of snagging of harness straps. Moreover, the garment is easy to don.
The harness may be sewn fast to the interior surface of the garment.
Preferably the rear of the garment has a connector to which a lanyard may be attached.
The garment may incorporate floats so that it can be used in environments where there is a risk of falling into water.
The garment may in certain preferred embodiments contain comfort padding and/or may be reinforced at areas prone to wear or damage.
The garment material may have an outer waterproof or water-resistant layer or coating.
The garment material may be flame-proof.
Specific embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings in which:
Figure 1 is a front view of a personal safety garment in accordance with the present invention and as worn by a user;
Figure 2 is a rear view of the garment of figure 1 ; and
Figure 3 is a perspective view of an alternative embodiment of the garment as worn by a user.
Referring now to the drawings, the exemplary safety garment is in the form of an overall or boiler suit 1 having leg, arm and torso sections la, lb, lc. The garment has a front opening Id for donning and removing the garment, the opening being closeable by a suitable releasable fastener le.
Sewn fast to the inside of the garment is a safety harness 2 comprising straps of webbing material that are arranged to provide two shoulder loops 2a that pass around the shoulder and down the front and rear of the torso section lc of the garment. These loops 2a are each connected to a thigh loop 2b that is disposed in an upper thigh region of the leg section 1 a of the garment. The harness 2 may incorporate an optional waist or chest belt 2c that is disposed transverse to the shoulder loops 2a. All of the strapping is sewn directly to the garment by stitching so that it cannot move relative thereto. The thigh loops are interconnected by a strap 2d that is also sewn to the garment in a groin region.
The thigh and shoulder loops 2a, 2b are connected by straps at the rear to a lanyard connector such as a D-shaped ring or karabiner 3, as is well known. In use, a fall-arrest lanyard 3 a is generally attached to this connector.
A D-ring connector may additionally or alternatively be disposed in the waist or chest area of the garment. This would provide an alternative anchoring point for the worker and is particularly applicable to workers on a platform of a sky climber, scissor lift or telescopic boom where it is necessary for the worker to be securely fastened within the bounds of the platform rather than being connected to a point overhead.
The garment is constructed from heavy duty material which may be waterproof and/or flameproof or coated with a protective material having one or both of such properties.
In use the garment is worn over the wearer's clothes in the same manner as an overall or boiler suit.
The integral nature of the overall and safety harness means that the garment can be tailored to fit an individual thereby eliminating the need for adjustment devices. This arrangement significantly reduces the tendency of harness straps to abrade and prolongs the life of the harness. Moreover, by having a tailor-made garment the harness becomes the personal responsibility of the wearer. Since the harness is sewn to the interior surface of the garment it can be easily inspected for wear. This enables safety checks to be conducted easily and eliminates the risk the harness snagging on surrounding equipment. By providing a garment there is no risk of the worker donning the harness in an incorrect manner.
Moreover, the garment eliminates the requirement for buckles or tightening straps on the harness thereby reducing the cost and manufacturing time of the garment.
The garment may be worn in other hazardous environments such as at sea by fishermen or oil rig worker. In such circumstances the garment may be fitted with floats or may be constructed from a material that is buoyant in water such as is known from flotation suits.
The garment may bear printed or embroided personal identification information such as the wearer's and employer's name and/or trade mark. It may also be coloured to provided identification of the worker's trade. For example, a blue garment for industrial workers, white for painters and a bright or fluorescent colour for emergency service workers.
In certain embodiments (not shown) the garment may incorporate comfort padding stitched to an appropriate position in the garment for scaffolders or construction workers who often need to carry equipment. Reinforcement material or padding may be provided in areas which are prone to wear (e.g. knees and elbows).
It will be appreciated that numerous modifications to the above described design may be made without departing from the scope of the invention as defined in the appended claims. For example, the harness straps may be made integral with the garment by means other than sewing.
Moreover, the garment may have belt loops in the waist area so that a tool belt may be worn. This would assist in additional tightening of the garment in the waist area so as to provide additional comfort in the event of a fall.
It is also to be appreciated that the harness configurations shown in the figures are intended as examples only and that the present invention is applicable to any configuration of safety harness.
