Description
PRISONER RESTRAINT SYSTEM
This is a division of application number 2,000,629 fled in Canada on 13 October, 1989.
Background of the Invention The present invention relates to a prisoner restraint system for transporting prisoners in a vehicle, and more particularly to a contoured transport seat back and cooperating restraint assembly for sup-porting and substantially immobilizing a rearwardly handcuffed prisoner while seated in a vehicle.
The transport of prisoners while in the custody of lacy enforcement personnel presents numerous risks to the safety of both the officers and prisoners involved. When not effectively restrained rearwardly handcuffed prisoners are subject to injury from poten-tially violent contact with the interior of the vehicle passenger compartment, particularly when the vehicle decelerates abruptly or negotiates roadway turns. With their hands cuffed behind them, prisoners are unable to use their hanc9s or arms for lateral support. Further, such prisoners are frequently intoxicated, under the influence of drugs, ill or otherwise incapacitated thereby further limiting their capacity to maintain a fully upright seated position. Such incapacitated persons are subject to vomiting, increasing risk of suffocation if the subject is not maintained upright.
Tra~aition.al belt restraints in cooperation with traditional rear seat configurations fail to pro-vide sufficient lateral support to a rearwardly cuffed prisoner. Prisoners could slip down in the seat so that the belt could become entangled around their necks.
Rearwardly handcuffed prisoners are also subject to injury to the arms, shoulders, wrists or back when restrained by seat and shoulder belts in traditional rear seats with hands pinned between the prisoner and the seat back.
When not Effectively restrained, prisoners are an obvious; potential risk to the safety of law enforcement pe~rsonnE~l during transport. The officer is particularly apt risk when in close proximity while reaching acro~;s the prisoner with both hands to secure a traditional belt restraint.
Tradlitional fabric seats present costly maintenance problems. Such seats are easily torn by the handcuffs worn by the prisoners occupying the vehicles.
Further, it i:c not uncommon for such prisoners to discharge bodily fluids which are difficult to~remove from fabric traditional upholstery. Traditional seats typically define an opening between the seat back and seat bottom where weapons or other contraband can be hidden by the prisoners occupying the seat.
The:>e and other problems result in increased maintenance time fo:r law enforcement vehicles, increased risk of bodily injury to law enforcement personnel, and increased liability on the part of governmental agencies for injuries sustained by those taken into custody.
In recent years, single-piece, hard-surfaced rear seats have been introduced in police and similar vehicles in an attempt to eliminate some of the deficiencies a ncountered in the use of traditional rear seats and prior art belt restraints. Such assemblies do have certain ad vantages over conventional seats, par-ticularly in connection with ease of cleaning and pre-y vention of hidden contraband. Such rear seats, however, fail to effectively immobilize in an upright position a seated prisoner for transport and fail to minimize an officer's proximity to a prisoner while engaging and tightening a belt restraint around such a potentially dangerous individual.. In fact, the hard slippery sur-face of such seats increase the likelihood that hand-cuffed prisoners will slide along the seat or be thrown about in the rear of: the police vehicle.
Summary of the Present Invention The present invention is directed toward a prisoner transport Neat back and a belt restraint assembly which cooperate to immobilize a seated, rear-wardly handcuffed prisoner in an upright position. This is accomplished according to the present invention by providing a co~ntourE~d seat back having a pair of brace portions which. engage the arms of the prisoner to pro-vide lateral s:uppori:. The seat back further includes a pocket means intermE~diate the brace portions for receiving the cuffed hands of the prisoner.
According to the exemplary embodiment of the invention, they seat back defines a substantially upright face having a pair of downwardly converging channels and a lower pocket: formed therein. In this embodiment a belt-type restraint means cooperates with the channels to maintain the pri~~oner in cooperative engagement with the seat back and provides frontal support to the prisoner. A preferred embodiment of restraint means is a seat belt assembly extending diagonally across the torso of the prisonE~r, the seat belt assembly .including a latch for engaging a receptacle secured to the vehicle. The latch includes a cinch for engaging and tightening they belt. The belt is secured at one end to the vehicle and at ithe opposite end to a cinching handle which is detac:hably mounted to the latch.
Accordingly, it is a principal object of the present inveni:ion to provide a contoured transport seat back which is adapted to provide lateral support to a rearwardly handcuffed prisoner.
It :is an accompanying object of the present invention to provide a contoured transport seat back which is adapted to receive the rearwardly cuffed hands of a prisoner.
~ It is an associated object of the present invention to provide means for engaging the shoulders of a prisoner so as to resist upward prisoner movement.
It is a further object of the present invention to provide restraint means adapted to provide frontal support to a prisoner.
It is a further object of the present invention to providle a seat belt assembly which cooper-ates with a transport seat back to restrain a prisoner rearwardly, frontally and laterally.

Detailed Description of the Invention Referring to FIG. 1, the rear passenger compartment 10 of a vehicle used to transport prisoners is shown. The compartment includes an exemplary retro-fitted seat 12 and exemplary belt restraint assembly 14, which cooperate to support and restrain a seated, rear-wardly handcu:Efed prisoner frontally, rearwardly, and laterally.
The exemplary seat 12 is of a single piece, resin-impregnated silicon fiber sheet mesh construction.
As best seen in FIG. 2 the seat includes a substantially upright face 16 having a pair of contoured seat backs 16a, 16b formed therein for accommodating two occupants in the passenger compartment 10. Each contoured seat back includes a pair of downwardly converging channels 18 in the upright face of the seat back for receiving and engaging the forearms of a prisoner. The upper extremities of the channels 18 each include an elbow recess 19 for receiving the occupant's elbows. Proxi-mate the converging lower extremities of the channels 18, an intermediates lower recessed portion defines a pocket 20 for receiving the cuffed hands of the prisoner. The poc~:et includes a sink 22 which defines an approximately 1~'4" recess into the pocket. The sink is filled with a resiliently deformable padding, such as foam rubber, to present a flush exterior pocket surface.
The padding cushions the hands and wrists of the occu-pant and provides additional space to accommodate the handcuffs. p,s may be seen in FIG. 4, in the exemplary embodiment, t:he lower pocket portion 21 forms the por-tion of the pocket most deeply recessed in the face of the seat back:. For example, the lower pocket portion 21 and elbow recesses 19 are approximately equally indented into the face 16 01the seat back.
The seat back face 16 includes a raised protuberance 23, bast seen in FIGS. 3 and 4, for supporting the lower middle back of the occupant. A
substantially triangular upper recessed portion 24 is located between thc~ diverging upper extremities of the channels 18 f:or receiving the shoulder blades of the occupant. Referring particularly to FIG. 4, an upper lip 26 protrudes horizontally outwardly of the face 16 providing a downwardly counteracting surface for engaging the shoulc9ers of the occupant and thereby resisting upward movement.
Rei:urning to FIG. 1, the seat also includes a rearwardly downwardly sloping seat bottom 44 which defines a pair of identical laterally concave troughs 44a, 44b each of wlhich is associated with a respective seat back 16a, 16b. The side walls of the troughs pro-vide lateral ~~ounterforce surfaces which serve to resist lower body lateral movement. The troughs allow addi-tional headroom for the occupants. As shown in FIG. 4 the seat back 12a a.nd seat base 12b each define respec-tive central axes which preferably intersect at a 90°
angle. The rearward, downward slope of the seat bottom 44 serves to urge t:he back of the occupant into engage-ment with the upright face 16 of the seat back 12a and resist forward slicling of the lower body of an occupant.
The troughs 44a, 44b are provided with a textured sur-face to further resist sliding of the lower body of the occupant.
According to the exemplary embodiment of the invention, the occupant is frontally supported using an adjustable seat be_Lt assembly 14 which, when tightened, urges the prisoner into cooperative engagement with the contoured seat back 16a, 16b. The seat belt assembly 14, as seen i.n FIGS. 1, 5, 6, 7 and 8, includes a belt 28 having one end :secured to a retractable spool 30.
The spool is attached by a mounting bolt to a standard plug in an adjacent wing wall of the vehicle. The spool includes conventional pin lock means for locking the belt at a desired Length of extension.
25 The unsecured end of the belt is directly connected to a cinching handle 32 as seen in FIG. 7.
The seat belie assembly 14 also includes a latch 34 which includes a cinch 36 for engaging and tightening the belt, a hand:Le engaging tang 38 for detachably engaging the cinching handle,, and a latching portion 40 for mating engagement with a buckle 42 secured to the vehicle. As best shown in FIG. 7, the latching portion and cinch 40, 36, respectively, of latch 34 are substan-tially coplanar. Tihe handle-engaging tang 38 is offset from the plane of t'he latch so as to project outwardly of the occupant. The handle-engaging tang includes an aperture 38a :Eor mating engagement with a~resilient button 39 within a slot 33 in handle 32. The resilient button may be of fabric such as Velcro'", rubber, or any other material which will interengage with the aperture 38a to provide some resistance to removal of the cinch-ing handle from the supporting tang. FIG. 8 shows an alternative cinching handle 32 molded out of plastic having an integral arm 35 with a button 39 formed thereon. The arm i.s resiliently movable so as to enable the button to engage and disengage from the aperture 38a in the tang 38. Access to the resilient arm is provided by a cap 37 which snaps over the well containing the arm.
As seen :in FIGS. 1, 2 and 4 the buckle 42 of the belt assembly :is supported outwardly of the seat by a semi-rigid belt lProjection 43 having a flexible segment proximate the buckle. The end of each belt pro-jection opposite the buckle is mounted to a bracket 41 which is secured to the vehicle. The buckle 42 may include a guide for directing the male latching portion 40 of the latch into the female receptacle; of the buckle.
In operation, a rearwardly cuffed prisoner is seated in the passenger compartment 10 and positioned -g-for cooperative engagement with one of the seat backs . 16a, 16b. WhE:n so positioned, the forearms of the prisoner are received in the downwardly converging chan-nels 18. The law enforcement officer then grasps the cinching hand:Le 32, which is attached to latch 34 as shown in FIGS 1 and 5, with one hand and directs the latching portion 40 diagonally across the chest of the occupant toward the buckle 42. The belt 28 is drawn out of the retractable spool 30 and positioned diagonally across the chest of the occupant. The latching portion 40 is then inserted into the buckle 42 and retained therein by operation of the buckle. The cinching handle 32 may then be disengaged from the latch 34 by pulling the cinching handles away from the buckle 4'2 as shown in FIG. 7 thereby overcoming and releasing the engagement between the aperture 38a and the button 39 within slot 33 of the cinching handle. Following this release of the handle, continued pulling by the officer in the direction shown draws any residual belt slack through the cinch portion 36 thereby urging the prisoner into cooperative engagement with the contoured seat back.
When the belt is fully tightened, the cinching handle 32 may be remounted to the handle receiving~tang 38 of latch 34. The belt: retains the occupant in cooperative engagement with the channels 18, pocket 20, upper recessed portion 24 and upper lip 26, thereby safely and effectively immobi".Lizing the prisoner for transport. In ' particular, the prisoner is provided with lateral sup-port by the engagernent of the forearms with channel walls 18a, 18c when the vehicle negotiates right-hand turns or chawnel walls 18b, 18d when the vehicle nego-tiates left-hand turns. The channel walls provide lateral count~erforce surfaces having a vertical com-ponent to resist lateral movement of the occupant.
The outward offset of the handle-engaging tang 38 maintains the handle 32 away from the body of the occupant thereby preventing potentially harmful contact between the occupant and handle during transport, and facilitating engagement and removal of the cinching handle with the tangs.
The seat 12 may also be used as a conventional seat to transport persons not handcuffed or those hand-cuffed in front. I:n such applications the protuberance 23, the upper recessed portion 24 and the upper lip 26 comfortably engage the lower back, shoulder blades and shoulders, respectively, of an occupant.
The term:. and expressions which have been employed in the foregoing abstract and specification are used therein as terms of description and not of limita-tion, and there is no intention in the use of such terms and expressions of excluding equivalents of the features shown and described or portions thereof, it being recognized that the scope of the invention is defined and limited only by the claims which follow.

FIG.. 8 is a side sectional view of an alternative exemplary cinching handle.
Detailed Description of the Invention Referring to FIG. 1, the rear passenger compartment 10 of a vehicle used to transport prisoners is shown. The compartment includes an exemplary retro-fitted seat 12 and exemplary belt restraint assembly 14, which cooperate to support and restrain a seated, rear-wardly handcu:Efed prisoner frontally, rearwardly, and laterally.
The exemplary seat 12 is of a single piece, resin-impregnated silicon fiber sheet mesh construction.
As best seen in FIG. 2 the seat includes a substantially upright face 16 having a pair of contoured seat backs 16a, 16b formed therein for accommodating two occupants in the passenger compartment 10. Each contoured seat back includes a pair of downwardly converging channels 18 in the upright face of the seat back for receiving and engaging the forearms of a prisoner. The upper extremities of the channels 18 each include an elbow recess 19 for receiving the occupant's elbows. Proxi-mate the converging lower extremities of the channels 18, an intermediates lower recessed portion defines a pocket 20 for receiving the cuffed hands of the prisoner. The poc~:et includes a sink 22 which defines an approximately 1~'4" recess into the pocket. The sink is filled with a resiliently deformable padding, such as foam rubber, to present a flush exterior pocket surface.
The padding cushions the hands and wrists of the occu-pant and provides additional space to accommodate the handcuffs. p,s may be seen in FIG. 4, in the exemplary embodiment, t:he lower pocket portion 21 forms the por-tion of the pocket most deeply recessed in the face of the seat back:. For example, the lower pocket portion 21 and elbow recesses 19 are approximately equally indented into the face 16 01the seat back.
The seat back face 16 includes a raised protuberance 23, bast seen in FIGS. 3 and 4, for supporting the lower middle back of the occupant. A
substantially triangular upper recessed portion 24 is located between thc~ diverging upper extremities of the channels 18 f:or receiving the shoulder blades of the occupant. Referring particularly to FIG. 4, an upper lip 26 protrudes horizontally outwardly of the face 16 providing a downwardly counteracting surface for engaging the shoulc9ers of the occupant and thereby resisting upward movement.
Rei:urning to FIG. 1, the seat also includes a rearwardly downwardly sloping seat bottom 44 which defines a pair of identical laterally concave troughs 44a, 44b each of wlhich is associated with a respective seat back 16a, 16b. The side walls of the troughs pro-vide lateral ~~ounterforce surfaces which serve to resist lower body lateral movement. The troughs allow addi-tional headroom for the occupants. As shown in FIG. 4 the seat back 12a a.nd seat base 12b each define respec-tive central axes which preferably intersect at a 90°
angle. The rearward, downward slope of the seat bottom 44 serves to urge t:he back of the occupant into engage-ment with the upright face 16 of the seat back 12a and resist forward slicling of the lower body of an occupant.
The troughs 44a, 44b are provided with a textured sur-face to further resist sliding of the lower body of the occupant.
According to the exemplary embodiment of the invention, the occupant is frontally supported using an adjustable seat be_Lt assembly 14 which, when tightened, urges the prisoner into cooperative engagement with the contoured seat back 16a, 16b. The seat belt assembly 14, as seen i.n FIGS. 1, 5, 6, 7 and 8, includes a belt 28 having one end :secured to a retractable spool 30.
The spool is attached by a mounting bolt to a standard plug in an adjacent wing wall of the vehicle. The spool includes conventional pin lock means for locking the belt at a desired Length of extension.
25 The unsecured end of the belt is directly connected to a cinching handle 32 as seen in FIG. 7.
The seat belie assembly 14 also includes a latch 34 which includes a cinch 36 for engaging and tightening the belt, a hand:Le engaging tang 38 for detachably engaging the cinching handle,, and a latching portion 40 for mating engagement with a buckle 42 secured to the vehicle. As best shown in FIG. 7, the latching portion and cinch 40, 36, respectively, of latch 34 are substan-tially coplanar. Tihe handle-engaging tang 38 is offset from the plane of t'he latch so as to project outwardly of the occupant. The handle-engaging tang includes an aperture 38a :Eor mating engagement with a~resilient button 39 within a slot 33 in handle 32. The resilient button may be of fabric such as Velcro'", rubber, or any other material which will interengage with the aperture 38a to provide some resistance to removal of the cinch-ing handle from the supporting tang. FIG. 8 shows an alternative cinching handle 32 molded out of plastic having an integral arm 35 with a button 39 formed thereon. The arm i.s resiliently movable so as to enable the button to engage and disengage from the aperture 38a in the tang 38. Access to the resilient arm is provided by a cap 37 which snaps over the well containing the arm.
As seen :in FIGS. 1, 2 and 4 the buckle 42 of the belt assembly :is supported outwardly of the seat by a semi-rigid belt lProjection 43 having a flexible segment proximate the buckle. The end of each belt pro-jection opposite the buckle is mounted to a bracket 41 which is secured to the vehicle. The buckle 42 may include a guide for directing the male latching portion 40 of the latch into the female receptacle; of the buckle.
In operation, a rearwardly cuffed prisoner is seated in the passenger compartment 10 and positioned -g-for cooperative engagement with one of the seat backs . 16a, 16b. WhE:n so positioned, the forearms of the prisoner are received in the downwardly converging chan-nels 18. The law enforcement officer then grasps the cinching hand:Le 32, which is attached to latch 34 as shown in FIGS 1 and 5, with one hand and directs the latching portion 40 diagonally across the chest of the occupant toward the buckle 42. The belt 28 is drawn out of the retractable spool 30 and positioned diagonally across the chest of the occupant. The latching portion 40 is then inserted into the buckle 42 and retained therein by operation of the buckle. The cinching handle 32 may then be disengaged from the latch 34 by pulling the cinching handles away from the buckle 4'2 as shown in FIG. 7 thereby overcoming and releasing the engagement between the aperture 38a and the button 39 within slot 33 of the cinching handle. Following this release of the handle, continued pulling by the officer in the direction shown draws any residual belt slack through the cinch portion 36 thereby urging the prisoner into cooperative engagement with the contoured seat back.
When the belt is fully tightened, the cinching handle 32 may be remounted to the handle receiving~tang 38 of latch 34. The belt: retains the occupant in cooperative engagement with the channels 18, pocket 20, upper recessed portion 24 and upper lip 26, thereby safely and effectively immobi".Lizing the prisoner for transport. In ' particular, the prisoner is provided with lateral sup-port by the engagernent of the forearms with channel walls 18a, 18c when the vehicle negotiates right-hand turns or chawnel walls 18b, 18d when the vehicle nego-tiates left-hand turns. The channel walls provide lateral count~erforce surfaces having a vertical com-ponent to resist lateral movement of the occupant.
The outward offset of the handle-engaging tang 38 maintains the handle 32 away from the body of the occupant thereby preventing potentially harmful contact between the occupant and handle during transport, and facilitating engagement and removal of the cinching handle with the tangs.
The seat 12 may also be used as a conventional seat to transport persons not handcuffed or those hand-cuffed in front. I:n such applications the protuberance 23, the upper recessed portion 24 and the upper lip 26 comfortably engage the lower back, shoulder blades and shoulders, respectively, of an occupant.
