Abstract

A vehicle seat (1) is provided having a squab (2) and a backrest (3), the backrest (3) being adjustable fore and aft with respect to the squab (2). The seat (1) may have substantially unaltered angular orientation of the backrest (3) in relation to the squab (2) in fore and aft positions. The lower portion of the backrest is connected to the squab by links (11) and the upper portion has spring loaded catches (12) each engageable in one of a pair of apertures (13) in the vehicle body bulkhead. <IMAGE>

Description

A VEHICLE SEAT This invention relates to adjustable vehicle seats and more particularly, although not exclusively, to a car seat with an aijlssable backre.st.
Lack of luggage space, is often a problem in modern cars, especially in small hatchbacks where a large boot area is impractical or inappropriate, owing to the need to keep the length of the vehicle as short as possible.
To a certain extent the problem of lack of luggage space in such cars has been minimised by providing a folding rear seat backrest to allow excess luggage to be placed over the rear seat. The disadvantage of this type of seat however is that it cannot be used to carry extra luggage and to seat a passenger at the same time.
The present invention is devised to overcome the above difficulties with known vehicle seats by providing a seat to allow significantly increased storage space behind the seat whilst still allowing the seat to be occupied by a passenger.
According to the present invention there is provided a vehicle seat having a squab and a backrest, the backrest being adjustable fore and aft with respect to the squab into fore and aft positions.
This has the advantage that luggage space behind the seat may be increased while still allowing the seat to be used by a passenger. The usable length of the squab is altered by the fore and aft adjustment of the backrest. This affords the further advantage that the seat, with the backrest in a forward position and the squab length reduced, can comfortably and safely seat a person with shorter legs, for example a child, with feet resting on the floor and back leaning against the backrest to allow use of a seatbelt if desired.
Angular orientation of the backrest to the squab may be substantially the same in fore and aft positions so that comfort is unaffected in said positions.
Upper and lower portions of the backrest may be separately adjustably mounted to the vehicle by upper and lower mountings respectively to provide a relatively simple and stable mounting for the backrest.
A first and a second lower mounting may be disposed substantially at either side of the backrest respectively, again to provide a stable mounting for the backrest at its lower portion. Each lower mounting may comprise a link pivotally connected to the lower portion of the backrest and to the squab, or to the vehicle body if more convenient, by first and second pivots respectively This arrangement will therefore allow the lower portion of the backrest to move in an arc fore and aft with respect to the squab.
To facilitate fore and aft adjustment of the backrest, stop means may be provided to limit fore and aft movement of the lower portion of the backrest.
A first and a second upper mounting may each be disposed substantially at either side of the backrest respectively. This is for convenient interaction of each upper mounting with a backrest and with part of the vehicle body, preferably a bulkhead.
Each upper mounting may have a first element on the backrest or vehicle body cooperable with one of a plurality of fore and aft spaced second elements on the vehicle body or backrest respectively whereby to secure the upper portion of the backrest to the vehicle in a forward or aft position. Each first element may comprise catch means and each second element may be an aperture to engage the catch means. Each catch means may conveniently be spring biased into engagement with a said cooperable aperture; release cf the catch means may he effected by moving same out of its cooperable aperture against the spring bias.
The upper mountings may secure not only the upper portion of the backrest, but the whole backrest in a forward or aft position to facilitate securing of the backrest in position.
The seat, in order to assist fore and aft adjustment, may be provided with biasing means whereby to bias the backrest towards said forward or aft positions. Spring assistance of the backrest to an aft position may be found the more desirable in this respect.
In order to afford further backrest adjustment fore and aft of the vehicle the seat may be movable fore and aft as a whole in addition to the adjustability of the backrest fore and aft with respect to the squab. Further versatility of luggage storage is thus possible.
The simplicity and versatility of the seat according to the invention will be appreciated from the above.
The invention will now be described by way of example with reference to the accompanying drawing of which: Figure 1 is a schematic side view of the vehicle seat according to the invention in an aft position, Figure 2 is a schematic side view of the seat shown in Figure 1 in a forward poSition, and Figure 3 is a schematic rear view of the seat taken in the direction I as shown in Figure 2.
Referring to the drawings, there is shown a seat 1 having a squab 2 and a backrest 3, a pair of lower mountings 4 connecting the squab 2 and a lower portion 5 of the backrest 3. An upper portion 6 of the backrest 3 is adjustably mounted to a vehicle body bulkhead 7 by a pair of upper mountings 8.
Each lower mounting 4 comprises a link 11 pivotally connected to the lower portion 5 of the backrest 3 and to the squab 2 by first and second pivots 9, 10, respectively.
Each upper mounting 8 has a first element in the form of a catch 12 spring biased into engagement with one of a pair of second elements, each comprising an aperture 13 set in the vehicle body bulkhead 7.
In Figure 1 two items of luggage 14 are shown behind the seat 1; in Figure 2 two larger items of luggage 15 are shown behind the seat 1.
Stop means 16 inhibit aft adjustment of the backrest 3 and provide added support for a passenger leaning against the backrest 3 when in an aft position.
To adjust the backrest 3 from its aft position as shown in Figure 1 to its forward position as shown in Figure 2, the catches 12 are first withdrawn from their respective apertures 13, the backrest 3 is then raised slightly and pushed forward, whereupon the lower portion 5 thereof will pivot about the pair of first pivots 9 and second pivots 10 as the backrest 3 moves forward. The catches 12 are engaged with forward apertures 13 to lock the backrest 3 in its forward position. The angular orientation of the backrest 3 to the squab 2 thus remains substantially the same in fore and aft positions respectively. Adjustment of the backrest 3 from the forward to the aft position is a mere reversal of the above procedure for forward adjustment of the backrest 3.
