Description
Technical field
The formula of the swaying mechanism that the present invention relates to child safety seat, also relates to a kind of locking mechanism, and this locking mechanism can be realizedThe control that diverse location is swayed.
Priority
Present patent application requires the priority of following patent application:
Application number is 22012901885, be entitled as " child safety seat with the improved formula mechanism of swaying " (CHILDSAFETYSEATWITHIMPROVEDRECLININGMECHANISM), the applying date is May 9 in 2012The priority of the Australian temporary patent application of day.
Be incorporated to by reference the full content of this application at this.
Background technology
Child safety seat for motor vehicles generally includes two kinds of chair types. The first is used for from neonate to sixThe baby of the moon. These seats are commonly referred to " seat of backward-facing ". These seats are placed in motor vehicles, make baby in faceTowards the rear to, like this, baby's back is towards the direct of travel of vehicle. In front end clashes into, impulsive force is by by safety seatBackrest absorbs.
From six months to four and half, the chair type of suggestion is formula forward-facing, and children are placed in stand up position. This classSafety seat has its band for children carrying and safety belt. This seat is by existing knee band and waistband or other connectionDevice is fixed on seat.
Obviously, it is desirable to a kind of backward-facing and safety seat of pattern forward-facing of having concurrently. For realizing this purpose, seatMust be designed to can be used as upright mode forward-facing, and be the pattern of formula backward-facing of swaying. Obviously, need to be at safety seatAnd between its base support member on automobile seat, carry out some and regulate, to reach various positions.
In addition, ideal is upright seat upward can be set level, to make the children of sleep feel comfortable. To supine seatThe degree that chair can be set level is conditional. If too set level, may produce " tunnel-effect ", i.e. youngster in the time being subject to clashing intoVirgin health moves forward with respect to band, will the lower part of the body be produced to large active force. Except the possibility that children deviate from from band, asFruit waistband is being pressed abdominal cavity or upper abdomen, also has serious injured risk.
Therefore, importantly the degree of swaying of safety seat forward-facing will be restricted.
To have the recline mechanism with preposition actuator children's seat talk about the Australian Patent that is found in applicant702416, the mode that the content of this application should be considered to is by reference incorporated to the application.
Under this background, research and develop the present invention just.

Detailed description of the invention
Referring to Fig. 1,2 and 4a, wherein show child safety seat seat assembly 1, comprising: the end of seat 12, seat 12Seat 10, the first recline mechanism and the second different recline mechanism, described the first recline mechanism can allow seat 12 with respect to base10, first swaying in range of movement and move between stand up position and the first recline location, described the second recline mechanism can allowSeat 12 is with respect to base 10, at the first recline location and further move between recline location.
Stand up position (seeing Fig. 1) and the first recline location (seeing Fig. 2) (, face for pattern forward-facing in vehicleFront) child safety seat 1. The first recline location be at child safety seat 1 in it forward-facing when pattern, seat 12With respect to the maximum amount of swaying that can allow of base 10.
Further recline location (as shown in Figure 4) provides the amount of swaying with respect to base 10 for seat 12, and this is obliquePartial amount is the amount of swaying needing when making seat 10 as the safety seat of backward-facing, and its degree of swaying is obviously larger.
Seat 12 is molded polymer component, comprises back part 12a and seat part 12b.
Each recline mechanism comprises the device for guiding seat 12, and this device collaboration type operation, to guide seat 12 phasesMove in its range of movement for base 10.
Referring to Fig. 5 a, to 5d, wherein the first recline device comprises first the leading of part 12b bottom side, seat that is attached to seat 12Bar 20, the end of this first guiding element bar 20 is positioned at and is formed at first pair of groove on base 10, and vis-a-vis (not figure inwardlyShow) in.
The second recline device comprises the second guide rod 30 of the rear end, back part 12a bottom that is attached to seat 12, wherein this secondGuide rod 30 extends in groove 32, and described groove 32 is formed at the center seat mount pad 34 extending out from base 10 rear ends.
Each recline mechanism further comprises locking device, for seat 12 is locked in to precalculated position, and unclamps seat12, it is moved in the scope of motion of swaying.
The first locking device 40 comprises the first latch body 42 of the part 12b bottom side, seat that invests seat 12, and it is used asLever arm, the pivotable tie point P from seat extends to the handle portion 44 of forefront.
By upwards pulling handle portion 44 (as shown in Figure 3), latch body 42 is rotated, and makes to invest latch bodyThe a pair of locking projection 46 of 42 bottom sides is retracted from supine locking hole 48, and described locking hole 48 is positioned at a pair of hanger 49Upper, described hanger 49 be fixed to base 10 or with base 10 be integral type moulding.
These hangers 49 comprise a row locking hole 48, and the locking hole at He rear, forefront corresponds respectively to of seat 12One recline location and stand up position. Middle locking hole 48 provides extra position adjustments.
Spring 35 extends between latch body 42 and the first guide rod 22. These springs 35 apply power to latch body 42,With in the time that handle 44 unclamps, guarantee that locking projection 46 is back to its locked position.
The second locking device 50 comprises the second latch body 52, and it is slidably located on the center seat mount pad of base 10The recess of 34 rear ends, and comprise (, the second latch body 52) shoulder, so that the first stop member 54 to be provided, prevent seat12 tilt to exceed the first recline location shown in Fig. 2, and the handle portion 45 of rearmost end is (as Fig. 4 b, 6a and 6b instituteShow). As shown in Figure 5 b, in the time that seat 12 arrives the first recline location, guide rod 22 against live the first stop member 54, therebyPrevent that seat 12 from swaying further.
In order to prevent seat 12 from swaying, to further recline location, (safety seat 1 can be used for towards rear mold on this positionFormula), by handle portion 56, the second latch body 52 is drawn outwardly and (seen Fig. 5 c), with movement against the biasing force of springStop member 54, and unclamp the second guide rod 30, thus make seat 12 can move to described further recline location.
The second latch body 52 further comprises recess, and it provides the second stop member 58, by this second stop member 58,The second guide rod 30 unclamps and returns forward under spring action, fastens subsequently, so that seat 12 remains on the second recline location,Until the operation of the handle 54 by the second latch body 52 is just released.
From above description, child safety seat 1 provides the convenient means that changes seat 12 degree of swaying, and also passes throughActuator or handle 44 are separated respectively with 56 on entity, provide when with pattern using forward-facing, prevented excessivelyThe effect of swaying. More specifically, in the time that child safety seat 1 is fixed on the forward-facing position in vehicle, for further obliquePartial handle 56 is disabled. And when handle 56 is while being available, the invention provides for making seat 12 further tiltedlyLean on the simple mechanism to certain position, wherein, child safety seat 1 can be used on backward-facing position.
It will be appreciated by those skilled in the art that and can make a large amount of distortion and/or correction to specific embodiments of the invention, and notDepart from the spirit or scope of the present invention. Therefore, embodiment described herein should be considered to illustrative and nonrestrictive.
Word in description " comprises ", should be understood to, imply and comprised described parts, element or step, or partsSet, set of steps, instead of get rid of any other parts, element or step, or component set, set of steps.
