Abstract

The invention discloses a kind of communications and transportation concave sponge safety headrests.Concave bench headrest is that head is rested the head in spill sponge bottom, and means of transport is (such as：Automobile, train, steamer, steamer etc.) it turns on one's side, and occur to protect head when the traffic accidents such as rolling；Head rest mitigates journey fatigue and convenient for resting in journey on spill headrest.

Description

Communications and transportation concave sponge safety headrest

Technical field：

The comfortable bench of traffic safety is used for transport facility, such as：Automobile, train, aircraft, the means of transports such as steamer On.

Background technology：

To prevent transport facility side collision, overturns, the protection of the accidents to occupant and driver such as overturns and roll, The seat design in the vehicles can be improved, the safety guarantee of driver and passenger are greatly improved；The seat of the vehicles removes Other than can taking, it can also become more comfortable, rest in taking transport process convenient for occupant, mitigate traffic Occupant's fatigue in journey.

Invention content：

Transport facility is turned on one's side, or when generation rollover accident, and it is most that head, which can collide and cause damage harm, Big.Maximum area uses sponge wrapping head, plays cushioned head colliding forces, plays a protective role to head.

Install sponge additional in the head on both sides of bench, with sponge wrapping head, sponge supporter supports, outside fabric or Leather wraps up sponge, forms one " concave structure " headrest, and the active force that sponge cushioned head collides with object is (as schemed 1)；When occupant is sitting in rest on bench, head relies on the sponge of head on both sides, gives occupant's head supporting force, reduces Occupant's muscular fatigue caused by shoulder neck and muscle of back are exerted oneself in traffic engineering.

To avoid the sponge of head on both sides from stopping the sight of passenger or so observation, and the facility usually taken, add The sponge of dress is front wide and rear narrow at " splayed configuration ".Try hard to 1, the head A of occupant as overlooked, leans against on headrest B, head on both sides C sponges And C ' sponges, buffering vehicles or so crash, give effect of impact power caused by head, mitigate or avoid head It is injured；When usually traffic accident does not occur for the vehicles, rest is loosened in head by head on both sides C sponges and C ' sponges.

Convenient for convenience of passenger riding, the sponge of head on both sides and headrest are linked to be an entirety, this entirety is sat with being inserted in It is support that the support link of headrest is supported on stool, using pillow centre as axle center, is flipped up 90 degree (such as Fig. 2A) or downward It turns over and turn 90 degrees (such as Fig. 2 B).Be inserted in supported on bench headrest support link be support, using rest the head on centre as axle center to Upper overturning downwardly turns over, and sponge hinders the sponge vacancy at the position of supporting rod, and the sponge of head on both sides is made to be stuck up to bench top It rises, or folds and snap over bench by back.

To ensure in transport process, occupant is sitting under drowsiness and sleep resting state on bench more comfortable, pillow Stress surface tilt backwards, avoid head from drooping forward and hang down, cause muscular fatigue.Such as M and M ' stress surface of Fig. 3, work as occupant It needs to keep erectting sitting posture, when needs are erect by headrest in head, as Fig. 3 (a) headrests rotate counterclockwise the N stress surfaces by resting the head on Stress；Or as Fig. 3 (b) headrest rotate clockwise headrest by N ' stress surface stress.

In general, when the passenger riding vehicles will enter sleep state, the backrest of bench is fallen can backward, make buttocks and the back of the body Stress supports the more comfortable body of body simultaneously in portion.Due to having certain thickness, then the bottom due to bench and bench before and after the body of people The construction of back rest supports point, if head will still be rested the head in headrest positions, is rested the head on when body falls backward by bench backrest It need be towards backrest direction retracted downward a distance (such as Fig. 5) of bench.Therefore, need pillow flexible distance compares up and down It is long.

Leant against on bench to ensure occupant erectting sitting posture and lying on the back, headrest can supporting head part, and do not lose seat Stool empties the upper edge middle section of bench backrest the package performance of body, and the sponge of headrest and head on both sides is embedded in seat Stool leans on back.If Fig. 5, headrest A are mounted on bench backrest B, the distance of stretch out and draw back of pillow A is increased.When passenger riding, headrest is pulled Up and down adjustment pillow height.Head on both sides sponge is flipped up expansion, is sleeved on head on both sides, plays the protective effect to occupant.

Occupant, which either erects sitting posture and still lies on the back, to be leant against on bench, and the sponge of head on both sides is fixed on bench and headrest Supporting rod on, only change the angle of inclination of headrest pillow, occupant is safer.Such as Fig. 6, two pieces of sponge A of head on both sides and A ' is mounted on headrest B has certain degree of hardness, and with a certain size power compressional deformation, the bullet of original form can be restored again by unclamping pressure Property backing material is such as：The materials such as sheet metal or engineering plastics are on M.M is connected to by the bent support bar H of bench backrest On bench backrest C.The B that rests the head on is rotated with lower end of resting the head on, 0 close to the face of bench bench backrest for fulcrum, the angle adjustment of pillow It to suitable position, is fixed by the buckle on M, realizes the adjustment of pillow angle.

Mounting knob on the supporter of shape is kept in the sponge of head on both sides and support sponge, convenient in tool traffic Journey moderately gusty air or when traffic accident occurs, occupant's hand handle handle keeps stablizing relatively for body trunk and head, is attached to seat On stool, make the head of occupant and trunk that roll be avoided to collide, occupant is protected oneself (such as Fig. 7) with the most safe posture for embracing head.

The metal support link of headrest and bench is processed into the erose structure in unified direction to the left or to the right, with buckle It is stuck in dentalation recess, headrest and head on both sides sponge is avoided to be slided up and down (such as Fig. 8) by external force.Headrest A need be adjusted When height, button E is pinned in extruding, buckles the erose structure that C and C ' is detached from the support link D and D ' of headrest and bench, head Pillow moves up and down adjustment position.Release button E, spring F active forces, buckle C and C ' be stuck in D and D ' erose structure on, Limitation headrest and head on both sides sponge are moved up and down by external force.

The sponge area of head two is thicker, and the effect of protection head is also bigger.Sponge can block sight too much.For Sight is not hindered, empties the part that head on both sides sponge blocks sight, convenient for the situation around the observation of driving tool (as schemed 9)。
