Abstract
The utility model discloses a headrest allowing a backup plate to be rotated and positioned at multiple angles. The headrest comprises a headrest cushion provided with a fixing strap. The side face of the headrest cushion is provided with a rotatable connecting mechanism which is connected with the backup plate. A connecting frame of the connecting mechanism is provided with a screw connected with the backup plate. The connecting frame is provided with a pawl shaft and a ratchet shaft, wherein a pawl and a ratchet provided with a plurality of teeth are installed on the pawl shaft and the ratchet shaft respectively, the ratchet is provided with a screw connected with the headrest cushion, a torsion spring is installed on the pawl shaft, a commutator segment is installed on the ratchet shaft, a transversely-bent strip which covers the ratchet is arranged at the upper end of the commutator segment, and the ratchet is provided with a retaining pin and a rewind pin. The headrest has the advantages that in the prior art, a backup plate mechanism is arranged on the side face of a headrest cushion, the backup plate can be rotated and positioned at the multiple angles, as a result, the headrest can be combined with the human body in the using process, the phenomenon that the head of the human body swings leftward and rightward is limited, and a good using effect can be guaranteed.
Description
Technical field
The utility model relates to a kind of head rest of the use of sleeping, specifically, be a kind of backup plate can multi-angle rotary the head rest of location.
Background technology
People are in order to work, to live, and often ride-on vehicles or boats and ships for a long time in the process of long-time ride-on vehicles or boats and ships, are easy to feel sleepy, drowsiness.More comfortable for can be sleepy in the process of long-time ride-on vehicles or boats and ships time, people have invented the head cushion being connected in vehicle or boats and ships headrest lifters, in use, unclamp the connecting band at head cushion rear portion, be looped around fastening in vehicle or boats and ships headrest lifters.Its weak point is: the head cushion of prior art, and without side backup plate mechanism, pad is at the neck of human body mostly, and the head of human body still can swing, and affects result of use.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of side backup plate mechanism that has is provided, and backup plate can be located by multi-angle rotary, in use can combine with human body, the head phenomenon that swings of restriction human body, guarantees the head rest that the backup plate of result of use can multi-angle rotary location.
The utility model backup plate can multi-angle rotary the technical scheme of head rest of location, comprise the head cushion with clamping band, the side of described head cushion is provided with rotatable bindiny mechanism and is connecting backup plate.
The link span of described bindiny mechanism is provided with screw and is connected with backup plate, and described link span is provided with pawl axis and ratchet shaft is installed with respectively ratchet and the ratchet with a plurality of ratchets, and described ratchet is provided with screw and is connected with head cushion.
Described pawl axis is installed with torsion spring, and one end of torsion spring heads on the baffle plate of link span, another side pressure ratchet.
Described ratchet shaft is installed with commutator segment, and the upper end of commutator segment is provided with transverse fold bar and covers on ratchet.
Described ratchet is provided with retaining nail and moves back sheet nail.
Described head cushion is wrapped in flexible substrate by flexible layer and makes.
Describedly by flexible layer, be wrapped in backup plate matrix and make.
The utility model backup plate can multi-angle rotary the beneficial effect of head rest of location be: in the side of prior art head cushion, backup plate mechanism is set, and backup plate can be located by multi-angle rotary, in use, can combine with human body, the head phenomenon that swings of restriction human body, can guarantee good result of use.
Accompanying drawing explanation
Fig. 1 be the utility model backup plate can multi-angle rotary the front view of head rest of location;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the part sectional view of Fig. 2;
Fig. 4 is the back view of Fig. 1;
Fig. 5 is the enlarged drawing at I place in Fig. 3;
Fig. 6 is that A in Fig. 5 is to view.
The specific embodiment
Backup plate shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 can multi-angle rotary the head rest of location, comprise the head cushion 1 with clamping band 3, the side of described head cushion 1 is provided with rotatable bindiny mechanism 5 and is connecting backup plate 2.
The link span 9 of described bindiny mechanism 5 is provided with screw 20 and is connected with backup plate 2, and described link span 9 is provided with pawl axis 10 and ratchet shaft 15 is installed with respectively ratchet 12 and the ratchet 7 with a plurality of ratchets 8, and described ratchet 7 is provided with screw 20 and is connected with head cushion 1.
Described pawl axis 10 is installed with torsion spring 11, and one end of torsion spring 11 heads on baffle plate 21, another side pressure of link span 9 and ratchet 12.
Described ratchet shaft 15 is installed with commutator segment 14, and the upper end of commutator segment 14 is provided with transverse fold bar 13 and covers on ratchet 7.
Described ratchet 7 is provided with retaining nail 17 and moves back sheet nail 18.
Described head cushion 1 is wrapped in flexible substrate 22 by flexible layer 23 and makes.
Describedly by flexible layer 23, be wrapped in backup plate matrix 24 and make.
During use, the clamping band of head cushion 13 junction buttons 6 are unclamped, be looped around fastening in vehicle headrest lifters.When needs regulate backup plate 2 angle, backup plate 2 is rotated along ratchet shaft 15 backward, after commutator segment 14 contacts with retaining nail 17, commutator segment 14 stops the rotation, ratchet 12 departs from the top that ratchet 7 rotates to transverse fold bar 13, then backup plate 2 is driven forward to 14 rotations of ratchet 7, commutator segment along ratchet shaft 15, when commutator segment 14 with move back after sheet nail 18 contacts, ratchet 12 rotates forward disengaging transverse fold bar 13 and falls between ratchet 8 and can use.Rotate backward backup plate 2 ratchet 12 translation-angles and fall between ratchet 8, realize backup plate 2 multi-angle rotary location.
