Description

A kind of comfort type bus seat

Technical field

The utility model relates to a kind of traveling comfort bus seat, belongs to seat apparatus technical field.

Background technology

Along with the fast development of Chinese national economy, highway passenger and freight throughput rate sharply increases.Highway is tied between various forms of transport by highway network, forms the transportation networks in town and country of extending in all direction, spread all over.

Compared with average highway, express highway has that road speed is fast, traffic potential is large, traffic cost is low, traffic safety, the outstanding advantage such as comfortable, its road speed exceeds more than 50% than average highway, traffic potential improves 2 ~ 6 times, and can reduce by more than 30% fuel oil consumption, reduce 1/3 motor vehicle exhaust emission, reduce by 1/3 traffic accident rate.

Express highway be automobile fast, safety, economy, comfortable operation create condition.In the comprehensive system of transport, road transport volume of passenger traffic proportion reaches more than 90%.

At present, motor passenger vehicle seat all can carry out the adjustment of back floating position substantially, but ubiquity seat surface and the poor situation of backrest comfort level, especially in long-term travel.Passenger easily produces tired meaning in long-term travel process, but seat comfort degree is poor, has had a strong impact on the journey ride experience of passenger.

Based on this, make subject application.

Utility model content

In order to overcome the defects such as comfort level existing for existing motor passenger vehicle seat is poor, safety performance is low, the utility model provides a kind of flexible adjustment, comfortable safe comfort type bus seat.

For achieving the above object, the technical scheme taked of the utility model is as follows:

A kind of comfort type bus seat, comprise chair cushion, backrest, left side are held up, right side is held up and pillow, described chair cushion is obliquely installed, and its tilt angle theta is 3-5 °; Chair cushion rear arranges rotating shaft, and backrest lower end and rotating shaft are that axle is connected, and in the middle part of described backrest, top 1/3-1/4 place is provided with projection forward, and the radian rad of this projection is 20-35; Pillow inserts above backrest by strut bar activity; Left side is held up to hold up with right side and is installed on chair cushion both sides respectively, and described left side is held up and to be held up with right side that be respectively arranged with can 360 ° of draw-in grooves rotated for what lay arm.

Further, as preferably:

The groove edge of described draw-in groove is set to round edge.

The packed layer of degree of deformation at 20-30mm is provided with in described chair cushion.

Be provided with recess in the middle part of described pillow, the degree of depth h of this recess is 20-50mm.

Described rotating shaft and chair cushion are for being fixedly connected with, and chair cushion cannot rotate around the axis, and described rotating shaft and backrest are for being flexibly connected, and backrest can rotate around the axis, thus the integral inclined degree of adjustment backrest.

The described backrest left and right sides is respectively arranged with left support and right support.

Described chair cushion tilt angle theta is 4 °.

The utility model bus seat adopts vehicle man-machine engineering principle, and with the 95th hundredths for designing requirement, take into full account the eco-physiological characteristic of people, what meet most of passenger takes requirement.Design according to anthropometric data, the main by weight of health is born by buttocks ischial tuberosity, and during rest, weight also be should bear in back, reduces thigh to the pressure of seat.Seat entirety has certain parcel, and passenger also freely can convert body position.Design backrest, lumbar support and handrail, backrest will take into full account waist heap curve shape, and chair cushion surface is designed according to human body distribution of pressure on the seat, and has certain thickness, hardness and permeability to air, and body weight can be uniformly distributed in ischial tuberosity region.

(1) chair cushion: in the present embodiment, the horizontal length of thigh when the degree of depth of chair cushion is less than sitting posture, in the utility model, the most preferred chair cushion degree of depth elects 500mm as; Chair cushion is too narrow, and passenger can be made not feel well; Chair cushion is too wide, and the both arms of passenger can outwards open.Be squeezed for avoiding the muscle of health both sides and dorso-humeral region muscle is stretched, in the utility model, most preferred chair cushion width is 510mm; In vehicle travel process, its running region mostly is express highway, moving velocity is at 100 kilometers/hour, conventional parallel chair cushion can cause passenger's slippage in vehicle travel process, safety is low, therefore, in the application, chair cushion is arranged in an inclined manner, and angle of inclination is excessive, be easily expressed to belly or belly, cause passenger uncomfortable, on the basis considering the speed of a motor vehicle and safety and traveling comfort, in the application, be 3-5 ° by the tilt angle theta of chair cushion, the high outside and low outside stability that ensure that passenger's sitting posture on the seat, in turn ensure that the comfort level of passenger.

(2) backrest: normal lumbar vertebrae (i.e. side viewing) on mistake shape face forms a prone radian, this physiological camber can make backbone have elasticity, the jerk that buffering and dispersion motion bring to trunk, in the utility model, the preferred heights of backrest is 410mm, backrest with human vertebra curve-shape electronic and back bodice curve for design reference, its length is as the criterion with neck, in the middle part of backrest, top 1/3-1/4 place is provided with projection forward, the radian rad of this projection is 20-35, make the waist of passenger consistent with its lumbar vertebrae sinuousness, while keeping natural curvature, passenger is facilitated to have a rest, along with the degree of dip of backrest increases gradually backward, its strong point also upwards shifts simultaneously gradually.

(3) packed layer: in the utility model, in chair cushion, packed layer is set, this packed layer 25mm(that allows to have an appointment is preferred, this degree of deformation controls at 20-30mm) distortion, both played a supporting role, also can be dispersed in the pressure on buttocks and thigh, the extruding that minimizing leg and thigh receive simultaneously.

(4) left side is held up and is held up with right side: the vertical distance of the elbow lower end that left side holds up the height held up with right side and human body ischium node to naturally droop to upper arm is close, and in the utility model, this is preferably dimensioned to be 245mm; Left side hold up to hold up with right side above draw-in groove is set respectively, for placing arm, the stability of strengthening sitting posture, and avoid through the collision of pedestrian to passenger; Draw-in groove is equipped with S. A., and hold up in left side, correspondence position that right side is held up arranges mounting hole, S. A. is installed in this mounting hole, and draw-in groove can 360 ° of rotations by S. A., for packing up for subsequent use or opening and using; The groove edge of draw-in groove is arranged to fillet structure, avoids draw-in groove to accidentally injure passenger.

The utility model carries out three dimensional design according to human body distribution of pressure on the seat, lumbar region curve according to human spine profile design, for passenger provides weight support; Backrest has the left and right sides and supports, and parcel property is good, and can carry out manual regulation, meets multi-angle regulatory demand, is particularly useful for passenger's long-term travel; Pillow has recess area, and neck area can provide support, and alleviates weariness from a tiring journey; The packed layer good permeability of chair cushion, degree of deformation is moderate, and passenger is taking in process the discomfort that can not occur because perspiration causes, and overall comfort level, parcel property and safety are all better than conventional bus seat.
